Description

Technical Field

[0001] This utility model belongs to the field of vegetable planting technology, specifically an automatic seedling picking and placing device for a vegetable transplanter. Background Technology

[0002] Vegetables are a staple food for people and also a major economic crop, so the efficiency of vegetable cultivation is particularly important. The development of transplanting machines reflects the use of agricultural machinery in my country. In the process of vegetable cultivation, if it is required that the spacing between plants, rows, and depth of transplanting be consistent, mechanical transplanting is necessary. The advantage of mechanical transplanting is that it can greatly improve the quality and yield of the planted crops.

[0003] Currently, to avoid the problem that manual sorting of vegetables cannot be replaced by mechanization, more and more people are starting to use seedling trays for pre-transplanting seedling cultivation. This allows mechanized material handling mechanisms to automatically pick up and place seedlings, greatly improving the level of mechanization, reducing manual labor, and increasing planting efficiency and costs. However, most existing seedling picking mechanisms based on seedling trays pull the seedlings out of the tray by directly clamping the seedling stems. This not only reduces the reliability of seedling picking but also easily damages the stems, even causing the roots to detach from the soil in the tray, affecting the transplanting quality, and sometimes even breaking the stems.

[0004] Therefore, it is necessary to develop an automatic seedling picking and placing device for vegetable transplanters to address the shortcomings of existing technologies. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides an automatic seedling picking and placing device for a vegetable transplanter, which has the advantages of high reliability and minimal damage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic seedling picking and placing device for a vegetable transplanter, comprising a machine head, a plurality of evenly distributed picking and placing mechanisms connected to one side of the machine head, a plurality of evenly distributed linkage components installed on the machine head, the plurality of linkage components corresponding one-to-one with the picking and placing mechanisms and communicating with each other, a drive mechanism provided on the machine head, the upper end of the drive mechanism being connected to the bottom of the plurality of linkage components, a drive motor provided inside the machine head, the output end of the drive motor being connected to the end of the drive mechanism away from the linkage components, a mounting frame connected to the other side of the machine head, and the machine head being connected to the control head on the agricultural machinery through the mounting frame; The picking and throwing mechanism includes two connecting plates fixedly installed on the machine head. The ends of the two connecting plates away from the machine head are respectively connected to a first picking claw and a second picking claw. The bottom of the first picking claw and the second picking claw are both provided with inclined piston chambers. A piston rod is sealed inside the piston chamber. The lower end of the piston rod is inserted into the soil clod in the seedling tray. The two piston rods are symmetrical with respect to the center of the seedling tray.

[0007] Furthermore, a connecting pipe is connected to the top of both the first and second grabbing claws. One end of the connecting pipe is connected to the top of the piston chamber in the first and second grabbing claws, and the other end of the connecting pipe is connected to the linkage assembly.

[0008] Furthermore, the outer surface of the piston rod is smooth, and the bottom of the two piston rods has a pointed structure on one side that is close to each other. The lower end of the piston rod is quickly inserted into the soil clod in the seed tray through this pointed structure.

[0009] Furthermore, the linkage assembly includes a connecting seat fixedly installed on the top of the two connecting plates. The connecting seat has a communicating cavity inside, and the ends of the two connecting pipes away from the piston cavity are respectively connected to the two ends of the communicating cavity.

[0010] Furthermore, a sealing sleeve is installed at the bottom of the two connecting plates, and a sealing cavity is opened at the bottom of the sealing sleeve. A connecting pipe is connected between the sealing sleeve and the connecting seat, and the upper and lower ends of the connecting pipe are respectively connected to the interior of the connecting cavity and the sealing cavity.

[0011] Furthermore, a piston plate is sealed inside the sealed cavity, and symmetrical connecting rods are fixedly connected to the bottom of the piston plate. The lower end of the connecting rods is connected to the upper end of the drive mechanism.

[0012] Furthermore, the drive mechanism includes a transmission rod disposed directly below the sealing sleeve. Both ends of the transmission rod are rotatably connected to the machine head via bearings. One end of the drive mechanism is connected to the output end of the drive motor in the machine head. The transmission rod is threaded with two left and right first sliding sleeves.

[0013] Furthermore, a linkage rod is provided directly above the transmission rod. The linkage rod is fixedly connected to the bottom of the connecting rod in a plurality of linkage components. An adjusting rod is rotatably connected inside the linkage rod. Two second sliding sleeves are threaded onto the outside of the adjusting rod. The lower end of the second sliding sleeve extends to the bottom of the linkage rod and is slidably engaged with the linkage rod. A shear rod is movably connected between the two corresponding second sliding sleeves and the first sliding sleeve.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: Due to the design of the drive mechanism, in conjunction with the linkage components, the drive motor in the machine head can control the extension and retraction of the two piston rods in the first and second picking claws through the drive mechanism and linkage components, thereby achieving an automatic and rapid picking effect. This avoids direct contact between the seedling picking mechanism and the plant itself, thus helping to prevent damage to the seedlings during the picking process.

[0015] Due to the arrangement of the picking and throwing mechanism, this utility model, with the cooperation of the first and second picking and throwing claws, allows the machine head to control the first and second picking and throwing claws in the several picking and throwing mechanisms to move to the front and rear ends of the left and right sides above a corresponding seedling tray under the action of the control head via the connecting plate. Then, with the cooperation of the drive mechanism and the linkage component, the two piston rods extend symmetrically downwards, thereby grabbing the symmetrical ends of the soil clods in the seedling tray and achieving a stable seedling throwing effect.

[0016] Due to the setting of the adjusting rod, the distance between the two second sliding sleeves can be adjusted by rotating the adjusting rod in cooperation with the linkage rod, thereby changing the distance between the upper ends of the two shear bars. Thus, in cooperation with the transmission rod and the two first sliding sleeves, the driving displacement of the piston rod is changed by the driving mechanism and linkage components when the drive motor in the machine head is in a fixed stroke state, so that the extension and retraction length of the piston rod can be adapted to the depth of the soil block in the pit.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 8 As shown, this utility model provides an automatic seedling picking and placing device for a vegetable transplanter, including a machine head 1. A plurality of evenly distributed picking and placing mechanisms 2 are connected to one side of the machine head 1. A plurality of evenly distributed linkage components 3 are also installed on the machine head 1. The plurality of linkage components 3 correspond one-to-one with the picking and placing mechanisms 2 and are interconnected with each other. A drive mechanism 4 is also provided on the machine head 1. The upper end of the drive mechanism 4 is connected to the bottom of the plurality of linkage components 3. A drive motor is provided inside the machine head 1. The output end of the drive motor is connected to the end of the drive mechanism 4 away from the linkage components 3. A mounting frame 5 is connected to the other side of the machine head 1. The machine head 1 is connected to the control head on the agricultural machinery through the mounting frame 5. The picking and throwing mechanism 2 includes two connecting plates 24 fixedly installed on the machine head 1. The ends of the two connecting plates 24 away from the machine head 1 are respectively connected to the first picking claw 21 and the second picking claw 22. The bottom of the first picking claw 21 and the second picking claw 22 are both provided with inclined piston chambers 25. The piston rod 26 is sealed inside the piston chamber 25. The lower end of the piston rod 26 is inserted into the soil clod in the seedling tray. The two piston rods 26 are symmetrical with respect to the center of the seedling tray. Due to the arrangement of the picking and throwing mechanism 2, with the cooperation of the first picking and throwing claw 21 and the second picking and throwing claw 22, the machine head 1 can control the first picking and throwing claw 21 and the second picking and throwing claw 22 in the picking and throwing mechanism 2 to move to the front and rear ends of the left and right sides above the corresponding seedling tray under the action of the control head through the connecting plate 24. Then, with the cooperation of the drive mechanism 4 and the linkage component 3, the two piston rods 26 extend symmetrically downward, thereby grabbing the symmetrical ends of the soil clods in the seedling tray and achieving the effect of stable seedling grabbing. Due to the setup of the drive mechanism 4, in cooperation with the linkage component 3, the drive motor in the machine head 1 can control the extension and retraction of the two piston rods 26 in the first picking claw 21 and the second picking claw 22 through the drive mechanism 4 and the linkage component 3, thereby achieving the effect of automatic and rapid grasping, avoiding direct contact between the seedling picking mechanism and the plant itself, thus helping to avoid damage to the seedlings during the seedling picking process.

[0021] The top of the first picking claw 21 and the second picking claw 22 are each connected to a connecting pipe 23. One end of the connecting pipe 23 is connected to the top of the piston chamber 25 in the first picking claw 21 and the second picking claw 22, and the other end of the connecting pipe 23 is connected to the linkage assembly 3.

[0022] Among them, the outer surface of the piston rod 26 is smooth, and the bottom of the outer surface of the two piston rods 26 is close to the tip structure. The lower end of the piston rod 26 is quickly inserted into the soil block in the hole plate through the tip structure. Because the lower end of the piston rod 26 has a pointed structure, it can be quickly and smoothly inserted into the soil block under the air pressure of the piston chamber 25, avoiding excessive pressure on the soil block in the seedling tray, thereby further reducing the damage to the seedling roots caused by the soil block pressure.

[0023] The linkage component 3 includes a connecting seat 31 fixedly installed on the top of two connecting plates 24. The connecting seat 31 has a connecting cavity 32 inside. The ends of the two connecting pipes 23 away from the piston cavity 25 are respectively connected to the two ends of the connecting cavity 32.

[0024] Among them, a sealing sleeve 33 is installed at the bottom of the two connecting plates 24, and a sealing cavity 35 is opened at the bottom of the sealing sleeve 33. A connecting pipe 34 is connected between the sealing sleeve 33 and the connecting seat 31, and the upper and lower ends of the connecting pipe 34 are respectively connected to the interior of the connecting cavity 32 and the sealing cavity 35.

[0025] The sealing cavity 35 is fitted with a piston plate 36, and the bottom of the piston plate 36 is fixedly connected with symmetrical connecting rods 37. The lower end of the connecting rods 37 is connected to the upper end of the drive mechanism 4. Due to the symmetrical connecting rods 37, when the linkage rod 44 is raised or lowered, the piston plate 36 can be controlled to move smoothly up and down along the inside of the sealing cavity 35 through the symmetrical connecting rods 37, thereby ensuring the smooth movement of the sealing cavity 35.

[0026] The drive mechanism 4 includes a transmission rod 41 located directly below the sealing sleeve 33. Both ends of the transmission rod 41 are rotatably connected to the machine head 1 via bearings. One end of the drive mechanism 4 is connected to the output end of the drive motor in the machine head 1. The transmission rod 41 is threaded with two first sliding sleeves 42 on the left and right sides.

[0027] Among them, a linkage rod 44 is provided directly above the transmission rod 41. The linkage rod 44 is fixedly connected to the bottom of the connecting rod 37 in several linkage components 3. An adjusting rod 46 is rotatably connected inside the linkage rod 44. Two second sliding sleeves 45 are threaded on the outside of the adjusting rod 46. The lower end of the second sliding sleeve 45 extends to the bottom of the linkage rod 44 and is slidably engaged with the linkage rod 44. A shear rod 43 is movably connected between the two corresponding second sliding sleeves 45 and the first sliding sleeve 42. Due to the setting of the adjusting rod 46, with the cooperation of the linkage rod 44, rotating the adjusting rod 46 can adjust the distance between the two second sliding sleeves 45, thereby changing the distance between the upper ends of the two shear rods 43. Thus, with the cooperation of the transmission rod 41 and the two left and right first sliding sleeves 42, the driving displacement of the piston rod 26 is changed through the drive mechanism 4 and the linkage assembly 3 when the drive motor in the machine head 1 is in a fixed stroke state, so that the extension and retraction length of the piston rod 26 can be adapted to the depth of the soil block in the pit.

[0028] Working principle and usage process of this utility model: The equipment is installed on the control head at the rear of the agricultural machinery via the mounting bracket 5. By controlling the movement of the machine head 1 back and forth and up and down via the control head, several picking and throwing mechanisms 2 on one side of the machine head 1 can be pushed onto the seedling tray system. The first picking and throwing claw 21 and the second picking and throwing claw 22 in each picking and throwing mechanism 2 are respectively located on both sides above the seedling tray. At this time, the drive motor in the machine head 1 runs, and the piston rod 26 in the first picking and throwing claw 21 and the second picking and throwing claw 22 in the picking and throwing mechanism 2 can be controlled by the drive mechanism 4 and the linkage component 3 to extend downward along the corresponding piston chamber 25 and insert into the soil clod at the root of the plant in the seedling tray. Then, the control head controls the machine head 1 and several picking and throwing mechanisms 2 to move upward simultaneously, so that the soil clod and the plant growing inside can be taken out from the seedling tray and moved above the seedling pot. Finally, with the cooperation of the drive mechanism 4 and the linkage component 3, the piston rod 26 retracts along the piston chamber 25, so that it is separated from the soil clod by the first picking and throwing claw 21 and the second picking and throwing claw 22 and falls into the seedling pot. Rotating the adjusting rod 46, under the constraint of the linkage rod 44, can cause the two second sliding sleeves 45 on the left and right to move away from or closer to each other, thereby changing the distance between the upper ends of the two shear rods 43. When the drive motor in the machine head 1 runs the same stroke again, the drive mechanism 4 pushes the linkage rod 44 upward to change the height, thereby changing the maximum distance that the drive mechanism pushes the connecting rod 37 and piston plate 36 to move upward along the sealing cavity 35. This allows the linkage assembly 3 and connecting pipe 23 to control the maximum distance of the piston rod 26 to extend and retract along the piston cavity 25, ensuring that it is suitable for grabbing soil clods of different depths.
