Description

Technical Field

[0001] The invention relates to the field of pepper seedling transplanting, and in particular to batch transplanting equipment used for pepper seedling cultivation. Background Art

[0002] Plug tray cultivation is an efficient and widely used method of raising pepper seedlings. Pepper seedlings cultivated using plug tray cultivation technology are easy to survive and grow quickly after transplanting, which can significantly improve the disease resistance and yield of seedlings. After the pepper seedlings are cultivated and grown in the plug tray, they need to be transplanted to the land for further planting. The traditional manual transplanting method is inefficient and is not suitable for batch transplanting of pepper seedlings.

[0003] Chinese patent application CN116806504 discloses a novel pepper seedling transplanting device, which includes a vibration plate, a sprocket drive, a groove wheel mechanism, a digging device, a slide, a bevel gear drive, and a slider mechanism; first, the unique effect of the vibration plate is used to neatly arrange the pepper seedlings into the corresponding slide, and then the pulse electromagnet is turned on and off to generate vibration, and the pepper seedlings enter the slide under the vibration. A baffle is provided inside, and the pepper seedlings reach the end along the slide under the traction of the baffle, and then the baffle is removed, and the seedlings will be neatly arranged in the slide. The sprocket drive is controlled by a motor, and the opening and closing of the digging device and the slider mechanism are controlled through a chain. This pepper seedling transplanter mainly adopts the principle of a vibration plate to allow the seedlings to be arranged into the slide and then planted in the soil.

[0004] The seedling tray is generally a terraced structure, and the cultivation space at the bottom is smaller than the space at the top. It is not convenient to use machinery to remove the seedlings from the tray without damaging their roots. For the pepper seedlings cultivated in the seedling tray in the early stage, the seedlings are first manually removed from the tray and then transplanted uniformly by mechanical equipment, which is inefficient. In addition, there is a certain time interval between the seedlings being taken out of the tray and being transplanted and planted in the soil. The seedlings during this period are prone to breakage and dehydration during transportation, which is not conducive to improving the survival rate of the pepper seedlings. Secondly, the planting interval of the pepper seedlings is affected by soil conditions and local climate. Some transplanting equipment is not convenient for adjusting the spacing between the batch transplanted pepper seedlings according to the actual spacing between the pits for pepper planting. During transplanting, the position of the pepper seedlings and the planting pits does not correspond accurately, causing some seedlings to tilt in the pits or out of the planting range of the pits. Manual adjustment is required later, affecting the efficiency of agricultural batch transplanting. Summary of the invention

[0018] 2. The present invention is provided with a shift drive component which can adjust the spacing of the transplanting components according to the actual spacing of the holes for planting the pepper seedlings. The planting density of the seedlings in the seedling hole tray is relatively high, and the transplanting components are moved and adjusted to the minimum spacing distance so that the pepper seedlings in the seedling hole tray can be taken out in batches.

[0039] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] See also Figure 1-Figure 10As shown, a batch transplanting device for cultivating pepper seedlings includes a frame 1, and the batch transplanting device also includes a mounting slide frame 21 slidably mounted on the frame 1, a seedling hole tray 22 for cultivating pepper seedlings embedded in the mounting slide frame 21, a mechanical arm assembly 3 mounted on the frame 1 to assist in transplanting pepper seedlings, and a fixed frame 4 rotatably mounted on the mechanical arm assembly 3; a slideway 41 is fixedly mounted on the fixed frame 4, and a plurality of slide seats 42 are slidably mounted in the slideway 41, and the slide seat 42 near the outermost position of the seedling hole tray 22 is fixed to the slideway 41 by bolts, and the left and right adjacent slide seats 42 are fixedly mounted on the slideway 41. The intervals are the same, and a transplanting assembly 43 is installed on the slide 42. The transplanting assembly 43 is used to transplant the pepper seedlings in the seedling tray 22 to the land in batches; a shift driving assembly 44 is provided on the fixed frame 4, and the shift driving assembly 44 is used to adjust the intervals between multiple slides 42 at equal intervals according to the distances between the pits for planting pepper seedlings on the land; the seedling tray 22 has a terraced structure, and the upper opening section is larger than the bottom planting section. The seedling tray 22 is installed on one side of the frame 1, and the position of the seedling tray 22 corresponds to the position of the laterally arranged transplanting assembly 43.

[0041] The seedling hole tray 22 is snap-fitted and installed in the installation slide frame 21. In the initial state, the spacing between the multiple transplanting components 43 arranged in parallel in a horizontal row is controlled to be at the minimum state. Each transplanting component 43 corresponds to the position of the hole in the seedling hole tray 22. The transplanting component 43 is controlled by the mechanical arm component 3 to move to the position directly above the seedling hole tray 22. Then, the pepper seedlings in the seedling hole tray 22 are clamped by the transplanting component 43. The transplanting component 43 is controlled by the mechanical arm component 3 to move the clamped pepper seedlings upward and separated from the seedling hole tray 22. According to the actual spacing of the planting holes on the land, the distance between the transplanting components 43 is adjusted by the shift drive component 44. Finally, the pepper seedlings clamped in the transplanting component 43 are accurately transplanted to the corresponding holes on the land by the mechanical arm component 3. The entire transplanting process of the pepper seedlings is very fast, which can avoid transportation breakage and dehydration during the transplanting process, thereby improving the survival rate of transplanted pepper seedlings.

[0042] See also Figure 3-Figure 8 As shown, the transplanting assembly 43 includes a lifting frame 431 fixed on the slide 42, four groups of guide seats 432 are installed at equal angles on the lifting frame 431, a slide groove 433 is opened on the guide seat 432, a slide frame 434 is slidably assembled on the guide seat 432 along the opening direction of the slide groove 433, and a plug plate 435 is fixedly installed on the slide frame 434; a lifting assembly for driving the four slide frames 434 to move synchronously is installed on the lifting frame 431.

[0043] The guide seat 432 has an inclined structure at the bottom, which controls the slide frame 434 to slide downward along the direction of the slide groove 433. The slide frame 434 drives the plug plate 435 to move downward synchronously, so that the plug plate 435 can be inserted into the bottom of the seedling hole tray 22 along the opening of the hole tray. The four groups of plug plates 435 are respectively inserted into different sides of the seedling hole tray 22 to clamp the pepper seedlings in the seedling hole tray 22. The plug plates 435 do not directly contact the roots of the pepper seedlings, and the pepper roots are not damaged during the clamping process. Then the transplanting assembly 43 is controlled to move upward through the mechanical arm assembly 3, and the plug plates 435 clamp the pepper seedlings and move upward synchronously to achieve rapid removal of the pepper seedlings in the seedling hole tray 22.

[0044] The lifting and lowering group can synchronously control the sliding frames 434 in four directions to move up and down, thereby realizing synchronous control of the four groups of plug boards 435 to move up and down.

[0045] See also Figure 3-Figure 8 As shown, the bottom of the plug plate 435 is in an inclined structure, and the slope of the inclined surface below the plug plate 435 is the same as the slope of the inner wall of the slide groove 433 and the seedling tray 22.

[0046] There is an inclined structure below the plug plate 435. When the plug plate 435 is controlled to slide obliquely downward along the direction of the slide groove 433, the plug plate 435 is fitted against the inner wall of the seedling hole tray 22 and moves obliquely downward. When the plug plate 435 moves to the bottom position of the seedling hole tray 22, the plug plate 435 is kept fitted against the inner inclined surface of the seedling hole tray 22. The root system of the pepper seedlings is not damaged during the downward movement of the plug plate 435, and the four groups of plug plates 435 respectively clamp the four positions corresponding to the planting soil in the seedling hole tray 22. When the transplanting assembly 43 is controlled to move upward by the robotic arm assembly 3, the pepper seedlings can be quickly removed from the seedling hole tray 22 through the plug plate 435.

[0047] See also Figure 6-Figure 8 As shown, the lifting assembly includes a cylinder 4341 fixed on a lifting frame 431, a disc 4342 is fixed to the telescopic end below the cylinder 4341, four groups of telescopic plates 4343 are telescopically connected at equal angles on the disc 4342, and the four groups of telescopic plates 4343 are fixedly assembled with four groups of sliding frames 434 respectively.

[0048] The operating cylinder 4341 pushes the disc 4342 to move downward, and the telescopic plate 4343 telescopically connected to the side of the disc 4342 moves downward synchronously. The telescopic plate 4343 is fixed on the slide frame 434 to drive the slide frame 434 to move downward synchronously. The slide frame 434 slides downward obliquely along the direction of the slide groove 433. During the process of the slide frame 434 sliding obliquely downward, the telescopic plate 4343 is pushed to move toward the inside of the disc 4342. By driving the disc 4342 to move up and down, the slide frame 434 can be driven to slide obliquely upward or downward on the outside of the guide seat 432, thereby adjusting the position of the plug plate 435 corresponding to the bottom of the lifting frame 431.

[0049] See also Figure 3-Figure 9 As shown, the shift drive assembly 44 includes an upper rotating rod 441 rotatably mounted on the slide 42, and a lower rotating rod 442 is also rotatably mounted on the slide 42, and the upper rotating rod 441 and the lower rotating rod 442 are cross-rotatably connected; the slide 42 near the outermost position of the seedling hole tray 22 is fixed to the slide 41 by bolts, and the upper rotating rod 441 and the lower rotating rod 442 on adjacent slides 42 are rotatably assembled; a threaded rod 443 is rotatably mounted on the fixed frame 4, and an internally threaded bracket 444 is threadedly assembled on the threaded rod 443, and the internally threaded bracket 444 is rotatably mounted on the second slide 42 near the seedling hole tray 22; the threaded rod 443 is interconnected with the output end of the motor fixed on the fixed frame 4.

[0050] According to the actual spacing of the holes for planting pepper seedlings on the land, the spacing between adjacent transplanting components 43 is equidistantly adjusted, and the threaded rod 443 is controlled to rotate. The threaded rod 443 causes the externally mounted internally threaded bracket 444 to move laterally through threaded transmission, and the internally threaded bracket 444 drives the slide 42 below to move synchronously. The slide 42 is engaged in the slide 41 and slides. During the movement of the slide 42, multiple upper rotating rods 441 and lower rotating rods 442 connected between adjacent slides 42 rotate synchronously. The rotation of the upper rotating rod 441 and the lower rotating rod 442 causes multiple slides 42 to engage in the slide 41 and slide. After the movement, the distance between adjacent slides 42 is the same, thereby achieving the purpose of equidistantly regulating the spacing between multiple transplanting components 43.

[0051] See also Fig.10 and Fig.11As shown, the mechanical arm assembly 3 includes a lower steering arm 31 rotatably mounted on the frame 1, an upper steering arm 32 is rotatably mounted on the lower steering arm 31, and the upper steering arm 32 is rotatably assembled with the fixed frame 4; a main electric drive telescopic rod 33 is rotatably mounted on the lower steering arm 31, and the telescopic end of the main electric drive telescopic rod 33 is rotatably assembled with the upper steering arm 32, a secondary electric drive telescopic rod 34 is rotatably mounted on the upper steering arm 32, and the telescopic end of the secondary electric drive telescopic rod 34 is rotatably assembled with the fixed frame 4; a driving rotating rod 311 is rotatably mounted on the frame 1, a driving bevel gear 312 is coaxially fixed on the driving rotating rod 311, a driving motor 313 is fixedly mounted on the frame 1, an output end of the driving motor 313 is connected to a driven bevel gear 314, and the driven bevel gear 314 is meshed and assembled with the driving bevel gear 312.

[0052] The driving motor 313 is operated to control the driving bevel gear 314 to rotate. The driving bevel gear 314 drives the driven bevel gear 312 to rotate through meshing transmission. The driven bevel gear 312 drives the lower steering arms 31 on both sides to rotate through the driving rotating rod 311. The main electric drive telescopic rod 33 on the lower steering arm 31 is operated. The main electric drive telescopic rod 33 is telescopic and pushes the upper steering arm 32 connected to the lower steering arm 31 to rotate. In the process of telescoping, the main electric drive telescopic rod 33 autonomously rotates and adjusts between the lower steering arm 31 and the upper steering arm 32. By controlling the rotation of the upper steering arm 32 and the lower steering arm 31, the moving position of the fixing frame 4 and the transplanting assembly 43 can be adjusted, so as to achieve the purpose of quickly transplanting the pepper seedlings in the seedling hole tray 22 to the soil pit through the transplanting assembly 43.

[0053] The auxiliary electric drive telescopic rod 34 on the upper steering arm 32 is telescopically moved, so that the fixed frame 4 connected to the upper steering arm 32 rotates accordingly. The auxiliary electric drive telescopic rod 34 is connected between the fixed frame 4 and the upper steering arm 32 and rotates and adjusts autonomously to control the rotation angle of the fixed frame 4. When the lower steering arm 31 and the upper steering arm 32 rotate, the fixed frame 4 and the transplanting assembly 43 are kept in a vertical state, so that the transplanting assembly 43 can be moved to plant pepper seedlings.

[0054] See also Figure 10-Figure 17 As shown, the lower steering arm 31 is provided with an autonomous pushing assembly 5 for pushing the mounting slide frame 21 to move and feed materials.

[0055] When the lower steering arm 31 rotates to control the transplanting assembly 43 to move the pepper seedlings into the hole on the ground, the lower steering arm 31 rotates downward by a large amplitude. During its downward rotation, the autonomous pushing assembly 5 is triggered, and the autonomous pushing assembly 5 pushes the mounting slide frame 21 to move a fixed distance, so that the pepper seedlings in different horizontal rows of the seedling hole tray 22 in the mounting slide frame 21 move to the position where the transplanting assembly 43 takes the materials, and the mechanical arm assembly 3 is kept to control the transplanting assembly 43 to take out the pepper seedlings in different horizontal rows in the seedling hole tray 22 at a fixed position, thereby simplifying the setting program of controlling the driving of the mechanical arm assembly 3.

[0056] See also Figure 10-Figure 17 As shown, the autonomous pushing assembly 5 includes a guide groove 51 provided on the frame 1, an equidistant moving bar 52 is slidably installed in the guide groove 51, a plurality of pushing card slots 521 are provided on the equidistant moving bar 52, a moving frame 53 is fixedly installed on the equidistant moving bar 52, the moving frame 53 is fixed on the mounting slide frame 21 and is slidably connected to the frame 1 by snapping; a pushing support rod 54 is rotatably installed on the lower steering arm 31, a limiting mechanism 55 for limiting the rotation range of the pushing support rod 54 is also installed on the lower steering arm 31, and the pushing support rod 54 is rotatably engaged and enters the pushing card slot 521.

[0057] When the lower steering arm 31 rotates downward to a certain position, the pushing support rod 54 on the lower steering arm 31 rotates and engages in the pushing slot 521 opened in the equidistant moving bar 52. At this time, the lower steering arm 31 continues to rotate downward, and the pushing support rod 54 engages in the pushing slot 521 to push the equidistant moving bar 52 to move along the direction of the guide groove 51. The pushing support rod 54 is connected to the lower steering arm 31 and rotates accordingly. The limiting mechanism 55 on the lower steering arm 31 limits the rotation range of the pushing support rod 54. The movement of the equidistant moving bar 52 drives the moving frame 53, the mounting slide frame 21, and the seedling hole tray 22 to move synchronously, so that the transplanting assembly 43 controls the transplanting of the pepper seedlings once, and the seedling hole tray 22 moves a fixed distance once, so that the pepper seedlings in different horizontal rows on the seedling hole tray 22 move to the position where the transplanting assembly 43 takes materials.

[0058] See also Figure 12-Figure 17 As shown, the limiting mechanism 55 includes a hollow column 551 rotatably mounted on the lower steering arm 31, a telescopic column 552 is telescopically connected to the hollow column 551, the telescopic column 552 is rotatably assembled with the push rod 54, and a limiting spring 553 is connected between the telescopic column 552 and the hollow column 551.

[0059] When the push rod 54 is connected to the lower steering arm 31 and rotates, the hollow column 551 is connected to the lower steering arm 31 and rotates, the telescopic column 552 is connected to the push rod 54 and rotates, and the telescopic column 552 is connected to the hollow column 551 through a limit spring 553 for elastic telescopic movement and adjustment. The elastic telescopic structure can limit the rotation range of the push rod 54 connected to the lower steering arm 31, and when the push rod 54 is kept from contacting the equidistant moving bar 52, the push rod 54 rotates to a fixed angle set on the lower steering arm 31.

[0060] See also Figure 12-Figure 17As shown, a positioning assembly 56 for limiting the moving position of the equidistant moving strip 52 is provided on the vehicle frame 1; the positioning assembly 56 comprises a column 561 fixed in the vehicle frame 1, a lifting column 562 is connected to the column 561 for sliding up and down, the lifting column 562 is longitudinally slidably connected to the vehicle frame 1, and a return spring 563 is connected between the lifting column 562 and the column 561; a plurality of positioning grooves 564 are provided on the lower end surface of the equidistant moving strip 52, the positions of the positioning grooves 564 correspond to the positions of the pushing slots 521, and the lifting column 562 moves up and is engaged with the positioning grooves 564.

[0061] When the equidistant moving bar 52 is pushed to engage in the guide groove 51 and slide, the lifting column 562 engaged in the positioning groove 564 below the equidistant moving bar 52 moves downward under the extrusion force. When the positioning groove 564 below the equidistant moving bar 52 moves to correspond to the top of another lifting column 562, the lifting column 562 moves upward under the thrust of the return spring 563, and the lifting column 562 engages in the positioning groove 564 below the equidistant moving bar 52. The moving position of the equidistant moving bar 52 on the frame 1 can be limited by the engaging structure, thereby maintaining the stability of the position of the adjustable installation slide frame 21 and the seedling tray 22.
