Description

Technical Field

[0001] The invention belongs to the technical field of rice seedling throwing machines, and in particular to a continuous conveying rice pot blanket seedling cutting and throwing machine. Background Art

[0002] Rice occupies an extremely important position in food production. There are three main ways to plant rice: direct seeding, transplanting and throwing. Although direct seeding is simple and convenient, it has problems such as poor connection between crop rotations and many weeds, diseases and insect pests. Although transplanting can solve the problems of poor connection between crop rotations and many weeds, diseases and insect pests to a certain extent, the rice transplanter still has problems such as complex structure, high cost, small number of rows, low work efficiency, and great damage to the seedling blanket during transplanting, and a long seedling regreening period.

[0003] The cultivation of rice seedlings is mainly divided into pot seedlings, blanket seedlings and pot blanket seedlings. Rice seedling throwing mainly throws rice pot seedlings. Since the pot seedlings come with soil pots, throwing does not damage the roots and the seedlings return to green quickly. However, this kind of rice seedling throwing machine for throwing rice pot seedlings needs to use special seedling trays for seedling cultivation, which makes it difficult to load and transport the seedlings during the transplanting process, the production efficiency is low, and the labor cost is high. The rice pot blanket seedlings take into account the advantages of the rice pot seedlings returning to green quickly and the rice blanket seedlings being curled and easy to load and transport. However, the work efficiency of cutting and throwing rice pot blanket seedlings in the prior art is low, and it is impossible to achieve continuous seedling transportation and throwing production.

[0004] Therefore, it is urgent to develop a continuous conveying rice pot blanket seedling cutting and transplanting machine to realize continuous seedling transportation and transplanting production and improve the mechanization and automation of transplanting. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the problems existing in the above-mentioned prior art and provide a continuous conveying rice pot blanket seedling cutting and transplanting machine to realize continuous seedling transportation and transplanting production and improve the mechanization and automation degree of transplanting.

The cutting and seedling throwing transmission device is connected to the stem lateral movement device and the rotary cutting device. The seedling blanket conveying power transmission device is connected to the primary conveying device and the strip cutting and seedling sending device. The primary conveying device, the strip cutting and seedling sending device and the rotary cutting device are arranged in sequence on the frame to form a seedling conveying station, a strip cutting station and a block cutting station. The primary conveying device transfers the rice pot blanket seedlings to the seedlings. The rice seedlings are transported from the rice seedling transporting station to the strip cutting station. The blanket pressing device is arranged above the strip cutting and seedling feeding device and is used to position the rice pot blanket seedlings. The strip cutting and seedling feeding device cuts the rice pot blanket seedlings into strips at the strip cutting station and transports them to the block cutting station. The rotary block cutting device cuts the strips into block seedlings at the block cutting station. The seedling dropping device is arranged directly below the rotary block cutting device. The block seedlings after being cut by the rotary block cutting device fall into the seedling dropping device to complete orderly seedling throwing. The stem transverse moving device is arranged at the block cutting station and is used to synchronously drive the seedling stems at the block cutting station to deviate during the block cutting operation to avoid interference between the seedling stems and the block cutting operation of the rotary block cutting device.

[0013] Power transmission route: The seedling blanket conveying power transmission device drives the secondary seedling sending active shaft and the linked cutting knife shaft group to rotate. The secondary seedling sending active shaft and the secondary seedling sending driven shaft transmit power through the secondary seedling sending conveyor belt.

The upper surface of the vine pressing rod and the frame exerts a certain force on the vine blanket or vines from both sides, which can prevent the vine blanket or vines from being pushed out of the upper surface of the frame, and can also increase the friction between the vine blanket or vine pressing rod and the upper surface of the frame, preventing the reciprocating cutting of the knife disc from disturbing the vine blanket or seedlings and reducing the conveying accuracy of the vine blanket or vines.

In order to prevent the seedling blanket from being pushed open due to insufficient cutting when cutting the seedling blanket, the cut seedlings from being accidentally pushed out, and to prevent the seedling blanket from being disturbed by reciprocating cutting, a blanket pressing device D is set at a distance before and after the seedling blanket is cut. The distance between the seedling pressing strip D6 and the mounting plate A8 is equal to the thickness of the seedling blanket. The seedling pressing strip D6 and the mounting plate A8 exert a certain force on the seedling blanket or seedling from both sides, which can not only prevent the seedling blanket or seedling from being pushed out of the plane of the mounting plate A8, but also increase the friction between the seedling blanket or seedling pressing strip D6 and the mounting plate A8, prevent the knife disc from reciprocatingly cutting and disturbing the seedling blanket or seedlings, and reduce the conveying accuracy of the seedling blanket or seedlings. The spacing between the seedling pressing strips D6 is equal to the spacing between two seedlings. The seedling pressing strip D6 is located between two connected seedlings. The width of the seedling pressing strip D6 is preferably about 20% of the width of the seedling, which can not only play the role of pressing the seedling blanket or seedlings, but also prevent the seedlings from being damaged by pressure. A cutting groove is provided in the middle of the pressing strip D6. When the cutting knife E12 is cutting, it forms a cutting edge with the pressing strip D6. The cutting edge of the cutting knife E12 extends into the cutting groove of the pressing strip D6. The seedling blanket is cut under the pressure positioning of the pressing strip D6, so that the strip cutting operation can be smoothly performed. By adjusting the vertical height position of the pressing strip adjustment seat D3, the spacing between the pressing strip D7 and the mounting plate A8 can be adjusted to make it suitable for seedling blankets of different thicknesses.

In this way, the first cutter shaft, the intermediate cutter shaft and the third cutter shaft form an integral structure, and the operation is linked. There is enough space between the cutters on the same cutter shaft group, and the cutters on the adjacent cutter shaft groups are also at a certain distance, ensuring that there are cutters distributed between each seedling of the blanket seedlings in the pot body, and ensuring that multiple cutters will not interfere with each other during the strip cutting operation.

[0065] See attached Figure 4 To Attachment Figure 6As shown in the figure, in one embodiment of the present invention, the seedling blanket conveying power transmission device L includes a seedling sending transmission box fixing plate L1, a first-level seedling sending driven wheel L2, a first-level seedling sending synchronous belt L3, a first-level seedling sending driving wheel L4, a seedling sending transmission box L5, a seedling sending and cutting power mechanism L6, a cutting power mechanism fixing bolt L7, a driving wheel L8, a synchronous belt L9, a driven wheel L10, a seedling sending transmission box connecting bolt L11, an intermediate shaft driving wheel L12, an intermediate shaft synchronous belt L13, a seedling sending transmission box fixing bolt L14, a first shaft driven wheel L15, an intermediate shaft driven wheel L16, a third shaft synchronous belt L17, a third shaft driving wheel L18, a first shaft synchronous belt L19, and a second-level seedling sending driven wheel L20.

The intermediate shaft driven wheel L16 and the intermediate shaft driving wheel L12 are fixed to the intermediate cutter shaft E4.

[0066] Combined with Figure 1 To Attachment Figure 6The principle of accurate rice seedling blanket transportation and strip cutting in this embodiment is briefly introduced as follows: the rice seedling strip cutting power mechanism L6 drives the third cutter shaft E6 to move through the synchronous belt L9, the third cutter shaft E6 drives the middle cutter shaft E4 to move through the third shaft synchronous belt L17, the middle cutter shaft E4 drives the first cutter shaft E3 to move through the middle shaft synchronous belt L13, and the cutter E12 installed on the third cutter shaft E6, the middle cutter shaft E4 and the first cutter shaft E3 cuts in the same direction to complete the strip cutting operation. The first cutter shaft E3 drives the secondary rice seedling sending active shaft E1 to move through the first shaft synchronous belt L19, the secondary rice seedling sending active shaft E1 drives the secondary rice seedling sending driven shaft E5 to move through the secondary rice seedling sending conveyor belt E9, and the pot-shaped rice seedling blanket C located on the secondary rice seedling sending conveyor belt E9 moves accordingly, the secondary rice seedling sending driven shaft E5 drives the primary rice seedling sending active shaft B1 to move through the primary rice seedling sending synchronous belt L3, and the primary rice seedling sending active shaft B1 drives the rice seedling sending conveyor belt B5 to move, completing the primary transportation of the pot-shaped rice seedling blanket C. The two-stage conveying method of seedling blanket conveying and seedling strip conveying can not only ensure the smooth connection of the front and rear seedling trays, but also make the seedling strip conveying more accurate. The seedlings move on the secondary seedling conveying conveyor belt E9, and the seedling blanket C in the pot contacts the small conveyor belt A3 and drives the small conveyor belt A3 to rotate through friction. The AB phase encoder A4 connected to the roller A6 receives the action signal, detects the seedling blanket conveying speed in real time, and adjusts the speed of the cutting power mechanism K1 in time through the PLC or single-chip control system to achieve accurate conveying. After the strip cutting operation, the seedlings are transported to the cutting station by the secondary seedling conveying conveyor belt E9.

[0067] See attached Fig. 9 and attached Fig.10 As shown in the figure, in one embodiment of the present invention, the rotary slicing device F comprises a rotary cutter shaft G1, a rotary cutter connecting member G2, and a rotary slicing knife group. The two ends of the rotary cutter shaft G1 are rotatably connected to the bearing A12 at the end of the frame A. The two rotary cutter connecting members G2 are respectively arranged at the two ends of the rotary cutter shaft G1. The rotary cutter connecting member G2 is a three-leaf shape. A total of three groups of rotary slicing knife groups are fixedly arranged between the two rotary cutter connecting members G2. The three groups of rotary slicing knife groups are evenly arranged at intervals of 120° in the circumferential direction. The slicing and throwing transmission device K drives the rotary cutter shaft G1 to rotate and then drives the rotary slicing knife group to rotate, so that the rotary slicing knife group can slicing the slender strips at the slicing station. In this way, the slicing and throwing transmission device drives the rotary cutter shaft to rotate one circle, and the three groups of rotary slicing knife groups complete a round of three slicing operations on the slender strips. By controlling the moving speed of the slender strips and the rotation speed of the rotary cutter shaft, the size of the slender strips can be controlled.

[0068] See the attached Fig. 9In one embodiment of the present invention, the rotary cutter connection member G2 is fixed to the rotary cutter shaft G1 by a cutter fixing pin G7. Each rotary dicing knife group includes a dicing knife shaft G3 and a dicing knife. The dicing knife shaft is fixedly arranged between two rotary cutter connection members. A plurality of dicing knives are evenly distributed on the dicing knife shaft G3. The dicing knives of the three dicing knife groups are arranged in a staggered manner in the horizontal direction. The axial distribution spacing of the plurality of dicing knife blocks of the three dicing knife groups is equal to the width of the slender.

[0069] See attached Fig. 9 To Attachment Fig.12 In order to conveniently introduce the specific principle of the cutting operation, the cutters on different cutting knife groups are labeled as cutting knife No. 1 G6, cutting knife No. 2 G4, and cutting knife No. 3 G5. From left to right (i.e., from the direction of the spring F8 to the boss F6), the adjacent cutting positions are labeled as cutting position No. 1 A31, cutting position No. 2 A32, and cutting position No. 3 A33. Among them, cutting knife No. 1 G6 cuts the seedlings at cutting position No. 1 A31, cutting knife No. 2 G4 cuts the seedlings at cutting position No. 2 A32, and cutting knife No. 3 G5 cuts the seedlings at cutting position No. 3 A33. Cutting knife No. 2 G4, cutting knife No. 3 G5, and cutting knife No. 1 G6 are arranged in a staggered manner in the horizontal direction to cut three adjacent saplings respectively. That is, three adjacent cutting positions are grouped together, and three cutting knives are used to cut them respectively, so that the adjacent cutting knives will not cut the same row of seedlings at the same time, avoiding the mutual involvement of adjacent seedlings; at the same time, the distribution spacing of the three groups of cutting knives is equal to the width of the seedlings, ensuring that each seedling can be cut into pieces. Fig.10 As shown in the diagram, the length of the cutting knife shaft G3 of each rotary cutting knife group is different, among which the length of the cutting knife shaft G3 of cutting knife No. 1 G6, cutting knife No. 2 G4, and cutting knife No. 3 G5 is successively shorter, so the seedling blocks cut by cutting knife No. 1 G6, cutting knife No. 2 G4, and cutting knife No. 3 G5 are distributed in a stepped manner. The seedling protection plate of the movable seedling board F7 and the seedling protection plate of the fixed seedling board F12 are tilted in the vertical plane, and the seedling protection plate of the movable seedling board F7 and the seedling protection plate of the fixed seedling board F12 are arranged in the same row. When the seedlings are transported to the cutting station by the secondary seedling conveyor belt E9 after the strip cutting operation, the slender stems of the seedlings enter the seedling protection plate accommodating cavity of the fixed seedling board F12 and the movable seedling board F7 and are vertically offset, so that the cutting knife will not cut the stems of the current seedlings during operation.

[0070] See attached Fig.12As shown in the figure, the seedlings at the cutting position A31, the cutting position A32 and the cutting position A33 are marked as the first seedling C1, the second seedling C2 and the third seedling C3 respectively. The cutting knife G6 and the cutting knife G4 are separated from each other by the inclined seedling protection board of the fixed seedling board F12, and the cutting knife G4 and the cutting knife G5 are separated from each other by the inclined seedling protection board of the fixed seedling board F12. That is, when the first seedling C1 and the second seedling C2 are cut, the two seedling protection boards of the fixed seedling board F12 offset the stems of the first seedling C1 and the second seedling C2 to avoid the cutting knife G6 and the cutting knife G4 of the first group. The cutting knife G5 of the previous group and the cutting knife G6 of the next group are separated by the inclined seedling protection board of the movable baffle F7, so that each group of cutting knives will not cut the stems of the seedlings at the current cutting position when working.

[0071] See attached Figure 5 , Attachment Figure 8 , Attachment Fig.12 and attached Fig.13As shown in the figure, because the cutting knife No. 3 G5 of the previous group is separated from the cutting knife No. 1 G6 of the next group by the inclined seedling protection plate of the movable baffle F7, after the third seedling C3 on the cutting position No. 3 A33 of the previous group is cut, before the first seedling C1 on the cutting position No. 1 A31 of the next group is cut, the third seedling C3 on the adjacent cutting position No. 3 A33 needs to be upright, otherwise the cutting knife shaft G3 of the cutting knife No. 1 G6 is relatively long, which will cut off the stem of the third seedling C3 on the cutting position No. 3 A33 of the next group. To solve this problem, a stem transverse moving device F is provided in one embodiment of the present invention to realize the position adjustment of the seedlings in the movable baffle F7. The stem transverse movement device F is installed on the front support D1 for pressing seedlings. The stem transverse movement device F includes a transverse movement shaft F1, a bearing seat F2, a fixing bolt F3, a cam mechanism, a movable seedling plate F7, a spring F8, a spring transverse movement fixing seat F9, a seedling plate fixing bolt F10, a seedling plate positioning nut F11, and a fixed seedling plate F12. The cam mechanism includes a cam opening device F4, a cam opening device fixing pin F5, and a boss F6. The cam opening device F4 is installed on one end of the transverse movement shaft F1 through the cam opening device fixing pin F5, the boss F6 and the spring transverse movement fixing seat F9 are fixed on the movable seedling plate F7, the cam opening device F4 is adjacent to the boss F6, the spring transverse movement fixing seat F9 is set on the other end of the transverse movement shaft F1, and the spring F8 is fixed between the spring transverse movement fixing seat F9 and the front support D1 for pressing the seedlings. When the spring F8 is in a relaxed state, it exerts elastic force on the crossbeam of the movable seedling plate F7, so that the movable seedling plate F7 is in the rightmost position, and the stems of the seedlings in the pot enter the movable seedling plate F7 and are guided to bend to the right (that is, the cam side). The block-cutting power mechanism K1 of the block-cutting and seedling-casting transmission device K drives the lateral movement shaft F1 to rotate, and the cam opening device F4 installed on the lateral movement shaft F1 contacts the boss F6, so that the movable seedling plate F7 moves horizontally to the left for a distance (i.e., the side of the spring F8), and the pot seedling stems guided by the movable seedling plate F7 return to a vertical state to avoid interference between the seedlings and the block-cutting knife No. 1 G6 during operation. After the cam opening device F4 is out of contact with the boss F6, the movable seedling plate F7 returns to its original position under the action of the spring F8. The lateral movement shaft F1 moves synchronously with the rotating cutter shaft G1, so that the movable seedling plate F7 moves horizontally when the block-cutting knife No. 1 G6 performs the block-cutting operation, so as to prevent the seedling stems from interfering with the block-cutting knife No. 1 G6.

[0072] The following is an introduction to the working principle of the linkage control of the stalk lateral movement and cutting of the seedling throwing machine in this embodiment: the cutting power mechanism K1 drives the rotary cutter shaft G1 to rotate, the rotary cutter shaft G1 then drives the rotary cutter connecting member G2 to rotate, the rotary cutter connecting member G2 drives the cutting cutter shaft G3 to rotate, and then drives the cutting cutter to move. Fig.12, as shown in FIG13. When the block cutter No. 1 G6 performs the block cutting operation, the block cutting power mechanism K1 drives the transverse shaft F1 to move, the cam opening device F4 installed on the transverse shaft contacts the boss F6, and the movable seedling plate F7 moves horizontally, so that the stems of the seedlings guided by the movable seedling plate F7 return to a vertical state, preventing the block cutter No. 1 G6 from interfering with the stems of the seedlings. When the block cutter No. 1 G6 completes the block cutting operation, the cam opening device F4 disengages from the boss F6, and under the action of the spring F8, the movable seedling plate F7 returns to its original position, and the stems of the seedlings guided by it bend, so that the block cutter No. 1 G6 can pass smoothly without interfering with the stems. Since the cutting knife No. 1 G6, the cutting knife No. 2 G4 and the cutting knife No. 3 G5 are arranged in a stepped manner, the fixed seedling board F12 is used between the cutting knife No. 1 G6 and the cutting knife No. 2 G4, and between the cutting knife No. 2 G4 and the cutting knife No. 3 G5 to press the seedlings sideways, the cutting knife No. 2 G4 and the cutting knife No. 3 G5 will not interfere with the fixed seedling board F12 when performing the cutting operation.

[0073] See attached Figure 2 and attached Figure 3 In one embodiment of the present invention, the block-throwing transmission device K includes a block-cutting power mechanism K1, a connecting bolt K2, a block-cutting power mechanism fixing bolt K3, a block-cutting power mechanism mounting member K4, a block-cutting transmission box fixing bolt K5, a block-cutting transmission box K6, a block-cutting transmission box connecting bolt K7, a block-cutting synchronous belt K8, a block-cutting driven wheel K9, a block-cutting driving wheel K10, a block-cutting transmission box fixing plate K11, a traverse device transmission box K12, a traverse device transmission box connecting bolt K13, a traverse device transmission box fixing bolt K14, a traverse driven wheel K15, a traverse synchronous belt K16, a traverse driving wheel K17, and a traverse device transmission box fixing plate K18. The block-cutting power mechanism K1 is fixed to the block-cutting power mechanism mounting member K4 by the block-cutting power mechanism fixing bolt K3, and is connected to the frame connecting plate A1 by the connecting bolt K2. The cutting power mechanism K1 is equipped with a cutting driving wheel K10 and a transverse driving wheel K17. The cutting driven wheel K9 transmits power to the cutting driving wheel K10 through the cutting synchronous belt K8. The cutting driven wheel K9 is installed on the rotating cutter shaft G1; the transverse device transmission box fixing plate K18 is fixed to the front support D1 of the rice seedling pressing through the fixing bolt F3 through the bearing seat F2, the transverse device transmission box K12 is fixed to the transverse device transmission box fixing plate K18 through the transverse device transmission box connecting bolt K13, the cutting transmission box fixing plate K11 is fixed to the transverse device transmission box K12 through the transverse device transmission box fixing bolt K14, the cutting transmission box K6 is connected to the cutting transmission box fixing plate K11 through the cutting transmission box connecting bolt K7, and is fixedly connected to the transverse device transmission box K12 through the cutting transmission box fixing bolt K5 through the cutting transmission box fixing plate K11.

[0074] Combined with Figure 2 To Attachment Fig.12The main principle of the block-cutting and seedling-throwing transmission device controlling the synchronous operation of the primary conveying device and the strip-cutting and seedling-feeding device is briefly introduced: the block-cutting power mechanism K1 moves the block-cutting driving wheel K10, drives the rotating cutter shaft G1 to move, and causes the various components installed on the rotating cutter shaft G1 to rotate and complete the block-cutting action. The transverse driven wheel K15 and the transverse driving wheel K17 transmit power through the transverse synchronous belt K16. The transverse driven wheel K15 is installed on the transverse shaft F1. The block-cutting power mechanism K1 moves the transverse driving wheel K17 to drive the transverse shaft F1 to rotate. The seedling-throwing machine of this embodiment can realize continuous seedling transportation, strip-cutting and block-cutting, and seedling-throwing operations. The seedling-cutting and strip-cutting power mechanism L6 operates uninterruptedly, the primary conveying device B and the strip-cutting and seedling-feeding device E operate continuously, and the AB phase encoder A4 detects the seedling blanket conveying speed in real time after receiving the seedling-feeding action signal, and adjusts the operating speed of the block-cutting power mechanism K1 in time through the control system to achieve accurate seedling delivery. The block cutting power mechanism K1 operates continuously, so that the rotary block cutting device G operates cyclically, and the block cutting operation is completed in a predetermined order, so that the block seedlings fall into the seedling dropping device H, and the block cutting and seedling throwing operation is completed.

[0075] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
