Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of transplanting machinery, in particular to a track type hand-automatic seedling throwing automatic vegetable transplanting machine. BACKGROUND

[0002] In the modern agricultural large-scale planting system, as a high-value economic crop, the planting efficiency and the survival rate of seedling planting of vegetables directly determine the economic benefits of the industry. As the core production link of vegetable planting, the transplanting operation needs to complete the whole process operation such as seedling taking, seedling throwing, seedling planting, soil covering and pressing within the suitable age period of seedlings. The technical requirements of the industry for operation efficiency, positioning accuracy and working condition adaptability are increasing year by year. In order to solve the efficiency bottleneck and cost problem of traditional manual transplanting, semi-automatic transplanting machines, fully automatic transplanting machines and other mechanized equipment have been gradually popularized and applied in the market.

[0003] At present, the mainstream transplanting machine generally adopts a track type walking system. By optimizing the ground pressure and traction force distribution, the stable operation performance of the machine in complex terrains such as muddy land, slope and facility greenhouse is ensured. At the same time, flexible maneuvering performance is provided to adapt to the operation scene requirements of different planting plots. The seedling tray conveying device configured by the transplanting machine bears the functions of seedling tray feeding and work station transfer, which can accurately convey the plug seedling to the operation work station of the seedling taking mechanism. The seedling taking mechanism adopts a planetary gear system to drive the jaw clamping and pulling type seedling taking, realizes the automatic seedling taking operation of the plug seedling, and conveys the seedling to the seedling planting device below to complete the planting operation of the vegetable seedling.

[0004] In order to ensure the accurate alignment of the seedling and the seedling taking jaw, the displacement of the seedling tray conveying device needs to be adjusted to realize the coordinate alignment of the plug seedling and the jaw. However, the traditional seedling tray conveying device adopts a single fixed displacement mode, which can only realize the linear conveying of the seedling tray. It cannot conveniently adjust the spacing parameters between multiple seedling trays according to the actual operation requirements. If the spacing needs to be adjusted, the multiple seedling trays need to be disassembled and adjusted, which not only seriously reduces the operation efficiency, but also easily causes the seedling positioning deviation due to the mechanical disassembly error, affecting the seedling taking accuracy. In addition, during the clamping and pulling operation of the seedling taking jaw, affected by the poor consistency of the growth of vegetable seedlings, such as excessive growth of part of the root system and entanglement of the root hairs, the space of the nutrient soil in the plug is easily squeezed, causing the seedling soil clump to be tightly adhered to the inner wall of the plug. At this time, the seedling taking jaw directly executes the clamping and pulling action, which easily causes the seedling stem damage, soil clump cracking and other problems, seriously affecting the quality of vegetable transplanting and the normal growth and development of the seedling after planting.

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the protection scope of the present application.

[0040] Please refer to Figures 1 to 14 An embodiment is provided in the present application as shown in the drawings:

[0041] A caterpillar type hand-automatic seedling planting automatic vegetable transplanting machine, comprising a transplanting machine base 1, a support 2 is fixedly installed on the top of the transplanting machine base 1, a driving device 4 is arranged in the inside of the support 2, four conveying seats 5 are installed on the top of the support 2 through a displacement control device 7, the four conveying seats 5 are divided into two groups with two as a group, and the two groups of conveying seats 5 are symmetrical about the driving device 4;

[0042] A ejection device 8 is arranged in the driving device 4, the ejection device 8 comprises two support cylinders 81 which are symmetrically rotatably installed in the driving device 4, a plurality of support discs 82 are fixedly connected to the outside of the support cylinder 81, and a plurality of ejection assemblies 83 are arranged in the inside of the support cylinder 81;

[0043] Among them, the driving device 4 can first drive the ejection device 8 to realize the ejection of the seedlings in the seedling tray, and then drive the displacement control device 7 to realize the displacement control of the conveying seat 5, so as to realize the low-damage seedling taking after alignment;

[0044] The driving device 4 comprises a mounting seat 41 fixedly installed in the inside of the support 2, a driving shaft 42 is rotatably installed in the inside of the mounting seat 41, four seedling taking mechanisms 6 are installed on the outside of the driving shaft 42, four seedling planting devices 3 are slidably installed on the bottom of the support 2, and a motor 9 is fixedly installed on the outside of the mounting seat 41.

[0045] In actual application, as shown in the drawings, Figures 1 to 5 Before starting operation, two groups of seedling trays are placed on four groups of conveying seats 5 distributed symmetrically, wherein each group of conveying seats carries a seedling tray, and the distance between the conveying seats 5 is adjusted through the displacement control device 7;

[0046] As shown in the drawings, Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 9As shown, after the motor 9 is started, the driving shaft 42 in the driving device 4 is rotated, driving the four seedling taking mechanisms 6 mounted on the outside to rotate synchronously, forming a circulating seedling taking track. After the operator places the seedling tray in the conveying seat 5, the conveying seat 5, which is a standard configuration of the transplanting machine, drives the seedling tray in it to move downward in the vertical direction (the current mainstream driving methods include driving wheel transmission or vibration conveying). When the seedling tray reaches the bottom position of the conveying seat 5 (as shown in FIG. 4), it will enter the gap area between the support disc 82 and the inner wall of the bottom of the conveying seat 5. As the gap area becomes smaller (by adjusting the position of the support disc 82 in the conveying seat 5, the gap area can be made smaller), the friction between the support disc 82 on the outside of the support cylinder 81 and the seedling tray increases, thereby driving the two support cylinders 81 to rotate symmetrically, forming multi-point support for the bottom of the seedling tray, avoiding deformation of the seedling tray due to stress during ejection, and at the same time, when the ejecting assembly 83 in the support cylinder 81 rotates to the position corresponding to the hole of the seedling tray, the ejecting assembly 83 extends radially, applies a pushing force to the soil lump through the drainage hole of the seedling tray, and makes the soil lump and the inner wall of the hole pre-separate, reducing the damage to the seedling during seedling taking;

[0047] As shown in FIG. 4, after the ejection action is completed, the driving device 4 drives the displacement device 7 to displace the conveying seat 5 along the top of the support 2, so that the seedling after the ejection treatment is accurately aligned with the clamping position of the seedling taking mechanism 6, realizing the coordinate matching of the seedling tray and the seedling taking mechanism; Figures 2 to 5

[0048] As shown in FIG. 4, after the ejection action is completed, the driving device 4 drives the displacement device 7 to displace the conveying seat 5 along the top of the support 2, so that the seedling after the ejection treatment is accurately aligned with the clamping position of the seedling taking mechanism 6, realizing the coordinate matching of the seedling tray and the seedling taking mechanism; Figure 2

[0049] As shown in FIG. 4, after the ejection action is completed, the driving device 4 drives the displacement device 7 to displace the conveying seat 5 along the top of the support 2, so that the seedling after the ejection treatment is accurately aligned with the clamping position of the seedling taking mechanism 6, realizing the coordinate matching of the seedling tray and the seedling taking mechanism;

[0050] As shown in FIG. 4, after the ejection action is completed, the driving device 4 drives the displacement device 7 to displace the conveying seat 5 along the top of the support 2, so that the seedling after the ejection treatment is accurately aligned with the clamping position of the seedling taking mechanism 6, realizing the coordinate matching of the seedling tray and the seedling taking mechanism; Figures 3 to 8 ​​As shown, the transfer device 7 comprises a fixed seat 71 fixedly installed on the support 2, the inside of the fixed seat 71 is fixedly connected with a guide plate 74, the inside of the guide plate 74 is provided with four horizontal grooves, the bottom of each conveying seat 5 is slidably connected with an active block 72, the bottom of the active block 72 is fixedly connected with a roller 77, the roller 77 penetrates through the horizontal groove, the inside of the fixed seat 71 is slidably connected with a push plate 78, the inside of the push plate 78 is provided with four inclined grooves, the roller 77 penetrates through the inclined groove at the same time, the outside of the push plate 78 is rotatably connected with a threaded rod 75, the threaded rod 75 is threadedly connected with the fixed seat 71;

[0051] The top of the seedling device 3 is fixedly connected with a connecting seat 73, the connecting seat 73 is fixedly connected with the active block 72, the inside of the connecting seat 73 is rotatably connected with a reciprocating screw rod two 76, the inside of the connecting seat 73 is slidably connected with a connecting block 79, the connecting block 79 and the reciprocating screw rod two 76 form a screw pair transmission, the connecting block 79 is fixedly connected with the bottom of the conveying seat 5, the inside of the mounting seat 41 is rotatably connected with a driving rod 70, the reciprocating screw rod two 76 is slidably connected to the outside of the driving rod 70 through a pin block.

[0052] In actual application, before operation, the distance between the conveying seat 5 and the seedling device 3 is adjusted synchronously through the transfer device 7 according to the planting row spacing requirement of the vegetable variety: the operator rotates the threaded rod 75 outside the fixed seat 71, because the threaded rod 75 is threadedly connected with the fixed seat 71, when the threaded rod 75 rotates, the push plate 78 slides along the inside of the fixed seat 71; the four inclined grooves of the push plate 78 and the roller 77 at the bottom of the active block 72 form a sliding fit, and the roller 77 penetrates through the horizontal groove and the inclined groove of the guide plate 74 at the same time, wherein, because the roller 77 penetrates through the horizontal groove and the inclined groove, the horizontal groove limits the roller 77 to move only horizontally, when the push plate 78 slides, the inclined groove pushes the roller 77 under the push of the side wall, so that the roller 77 moves horizontally along the horizontal groove;

[0053] Because the active block 72 is slidably connected with the bottom of the conveying seat 5 on one hand, and is fixedly connected with the seedling device 3 through the connecting seat 73 on the other hand, when the active block 72 moves, it synchronously drives the conveying seat 5 to adjust the horizontal distance, and drives the seedling device 3 to slide along the bottom of the support 2 to adjust the distance, so as to ensure that the distance between the two matches the planting row spacing;

[0054] During operation, the inside of the mounting seat 41 of the driving device 4 drives the rod 70 to rotate under the power transmission of the motor 9; the reciprocating screw rod two 76 is slidably connected to the outside of the driving rod 70 through a pin block, the driving rod 70 rotates to drive the reciprocating screw rod two 76 to rotate synchronously, the reciprocating screw rod two 76 and the connecting block 79 outside the active block 72 form a screw pair transmission, so when the reciprocating screw rod two 76 rotates, the connecting block 79 drives the conveying seat 5 to slide horizontally along the top of the active block 72, realizing the horizontal adjustment of the conveying seat 5;

[0055] When the ejection assembly 83 of the ejection device 8 pushes the seedling in the seedling tray to pre-separate, the driving rod 70 drives the reciprocating wire rod two 76 to drive the conveying seat 5 to move, so that the seedlings are aligned with the clamping position of the seedling taking mechanism 6, and the seedling taking mechanism 6 completes clamping and pulling, and the reciprocating wire rod two 76 continues to drive the conveying seat 5 to move, so that the next group of seedlings is conveyed to the ejection and seedling taking position, thereby realizing continuous seedling taking operation.

[0056] As shown in Figure 2 , Figure 4 , Figure 9 , Figure 10 , Figure 11 and Figure 12 , the ejection assembly 83 comprises a push rod 831 rotatably connected to the inside of the mounting seat 41, the inside of the supporting cylinder 81 is fixedly connected with mounting sleeves 834 in groups of four, the inside of the mounting sleeve 834 is slidably connected with a sliding block 837, the inside of the mounting sleeve 834 is fixedly connected with a supporting block 835, the supporting block 835 is slidably connected to the inside of the sliding block 837, the spring four 836 is fixedly connected between the supporting block 835 and the inner wall of the sliding block 837, the end of the sliding block 837 away from the push rod 831 is fixedly connected with a push block 832, and the outer side of the push rod 831 is fixedly connected with top blocks 833 distributed in a spiral manner.

[0057] When the driving device 4 drives the ejection device 8 to work, the push rod 831 in the inside of the mounting seat 41 rotates synchronously, the top blocks 833 distributed in a spiral manner on the outer side of the push rod 831 make a circular motion with the push rod 831, the mounting sleeves 834 in the inside of the supporting cylinder 81 rotate synchronously with the supporting cylinder 81, when the mounting sleeve 834 rotates to a position opposite to the push rod 831, the top blocks 833 distributed in a spiral manner gradually contact the sliding block 837 in the inside of the mounting sleeve 834, and exert a radial pushing force on the sliding block 837.

[0058] Under the pushing force of the top blocks 833, the sliding block 837 slides along the inner wall of the mounting sleeve 834, and at the same time, the spring four 836 between the supporting block 835 and the inner wall of the sliding block 837 is compressed (as shown in Figure 11 , the supporting block 835 is fixedly connected to the inner side of the mounting sleeve 834 and slidably connected to the inside of the sliding block 837, so that the support of the top of the spring four 836 can be realized, and the sliding of the sliding block 837 will not be affected), when the sliding block 837 moves away from the push rod 831, the push block 832 fixedly connected to the end of the sliding block 837 synchronously extends out of the mounting sleeve 834 and extends into the hole through the drainage hole at the bottom of the seedling tray, so that a pushing force is exerted on the soil lump of the seedling, a separation gap is generated between the soil lump and the inner wall of the hole, and the adhesion between the soil lump and the inner wall of the hole is reduced.

[0059] With the continuous rotation of the push rod 831, when the top block 833 is out of contact with the sliding block 837, the spring four 836 releases the elastic potential energy, pushes the sliding block 837 to slide along the support block 835, drives the push block 832 to retract into the mounting sleeve 834, and completes a ejection cycle;

[0060] Due to the spiral distribution design of the top block 833, the push rod 831 can sequentially push the sliding blocks 837 in each mounting sleeve 834 during rotation, cooperate with the displacement of the conveying seat 5, and make the push block 832 sequentially eject the seedlings in the seedling tray, so that each seedling soil clump can be separated and treated, and the damage of the subsequent seedling taking mechanism 6 is reduced.
