Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to an onion stalk killer. Background Technology

[0002] The main purpose of killing onion seedlings is to cut off the seedlings on the ground before harvesting the onions, so that the onions can be harvested and processed later. This helps to improve harvesting efficiency, reduce labor intensity, and reduce the shading of the onion bulbs by the seedlings, thus promoting the maturation of the bulbs and improving their quality.

[0003] Onion stalk killing is usually done using a specialized onion stalk killing machine. This machine uses a power unit to drive the stalk-cutting component to rotate at high speed to break the onion stalk leaves. At the same time, the machine is also equipped with a ground wheel assembly to adjust the height and position of the stalk killing machine, ensuring that it moves stably and operates accurately in the field.

[0004] When adjusting the height of the seedling killer, the user needs to turn the two handwheels at the back of the killer to adjust the two ground wheel components. However, since the two handwheels do not turn at the same time, it is impossible to ensure that the adjustment of the two ground wheel components is consistent, which can easily cause asymmetric adjustment. In addition, the user needs to turn the handwheels twice to achieve overall adjustment, which is quite troublesome to operate. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: an onion stalk-killing machine, comprising a stalk-killing machine and a connecting frame. One end of the stalk-killing machine is fixedly connected to the connecting frame, and the other end of the stalk-killing machine is fixedly connected to an installation frame. An adjustment mechanism is fixedly connected to the end face of the installation frame, and two lifting mechanisms are fixedly connected to the end face of the installation frame. The moving end of the adjustment mechanism is fixedly connected to the lifting end of the lifting mechanism, and a leveling mechanism is fixedly connected to the surface of the lifting mechanism.

[0006] As an improvement to the above technical solution, the adjustment mechanism includes a fixed plate, a limiting block, a pin, a threaded rod, a lifting block, and a connecting rod. The fixed plate is fixedly connected to the end face of the mounting bracket. The fixed plate rotates and engages with the limiting block through holes on its surface. The fixed plate has multiple limiting holes on its surface. The pin is inserted into the limiting block through holes on its surface. The lower end of the pin extends into the interior of the limiting hole. The surface of the pin is provided with a rubber layer. The upper end of the limiting block is fixedly connected to a threaded rod. The upper end of the threaded rod is fixedly connected to a crank handle. The surface of the threaded rod is threadedly connected to a lifting block. The surface of the lifting block is fixedly connected to two connecting rods. One end of the connecting rod is fixedly connected to the lifting end of the lifting mechanism.

[0007] As an improvement to the above technical solution, the lifting mechanism includes a fixed sleeve, a sliding rod, a sliding block, and a ground wheel. The fixed sleeve is fixedly connected to the end face of the mounting frame. A sliding rod is slidably connected to the upper end of the fixed sleeve, and the upper end of the sliding rod is fixedly connected to a connecting rod. A sliding block is fixedly connected to the lower end of the sliding rod. The sliding block is slidably connected to the inner wall of the fixed sleeve, and a ground wheel is rotatably connected to the surface of the sliding block.

[0008] As an improvement to the above technical solution, the rice seedling cutter includes a chassis, a cover plate, a transmission box, a drive pulley, a first rice seedling cutter assembly, a second rice seedling cutter assembly, a first driven pulley, and a second driven pulley. The cover plate is mounted on the surface of the chassis, and the transmission box is mounted on the surface of the cover plate. The drive pulley is mounted on the output shaft end of the transmission box. The first rice seedling cutter assembly and the second rice seedling cutter assembly are rotatably connected in the middle of the chassis. The second driven pulley is mounted on the shaft end of the second rice seedling cutter assembly, and the first driven pulley is mounted on the shaft end of the first rice seedling cutter assembly. The first driven pulley is connected to the second driven pulley and the drive pulley respectively via two transmission belts.

[0009] As an improvement to the above technical solution, the leveling mechanism includes a bracket, an mounting strip, and a rubber baffle. The bracket is fixedly connected to the surface of the fixing sleeve, the mounting strip is installed on the surface of the bracket by screws, and the rubber baffle is fixedly connected to the lower end face of the mounting strip.

[0010] The beneficial effects of this utility model are:

[0011] When the height of the rice transplanter needs to be adjusted, the user only needs to turn the crank handle to simultaneously raise and lower the two sliding rods relative to the fixed sleeve. This allows adjustment of the distance between the ground wheel and the mounting frame, thereby adjusting the overall height of the rice transplanter. Once adjusted, the rotation position of the limit block can be locked using the pin. This ensures that the adjustment of the two lifting mechanisms is consistent, improving the overall adjustment symmetry and making operation convenient. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0019] Please see Figure 1-5 This utility model provides a technical solution: an onion stalk killing machine, including a stalk stalk 1 and a connecting frame 2. One end of the stalk stalk 1 is fixedly connected to the connecting frame 2, and the other end of the stalk stalk 1 is fixedly connected to the mounting frame 3. An adjustment mechanism 4 is fixedly connected to the end face of the mounting frame 3, and two lifting mechanisms 5 are fixedly connected to the end face of the mounting frame 3. The moving end of the adjustment mechanism 4 is fixedly connected to the lifting end of the lifting mechanism 5, and a leveling mechanism 6 is fixedly connected to the surface of the lifting mechanism 5.

[0020] In this implementation scheme, when the user needs to adjust the height of the rice transplanter 1, the rotating part of the adjusting mechanism 4 is rotated, thereby causing the lifting part of the adjusting mechanism 4 to rise or fall. The lifting part of the adjusting mechanism 4 simultaneously drives the lifting ends of the two lifting mechanisms 5 to rise or fall, thereby adjusting the height of the rice transplanter 1. When the adjustment is finished, the adjustment position of the adjusting mechanism 4 is locked. Therefore, the user only needs to rotate the rotating part of the adjusting mechanism 4 once to achieve the overall height adjustment of the rice transplanter 1. At the same time, since the lifting ends of the two lifting mechanisms 5 rise and fall at the same time, the degree of adjustment of the two lifting mechanisms 5 can be guaranteed to be consistent, improving the overall adjustment symmetry.

[0021] like Figure 3As shown, the adjustment mechanism 4 includes a fixed plate 41, a limiting block 42, a pin 44, a threaded rod 46, a lifting block 48, and a connecting rod 49. The fixed plate 41 is fixedly connected to the end face of the mounting bracket 3. The fixed plate 41 is rotatably engaged with the limiting block 42 through holes opened on its surface. The surface of the fixed plate 41 is provided with multiple limiting holes 43. The pin 44 is inserted into the limiting block 42 through the holes opened on its surface. The lower end of the pin 44 extends into the interior of the limiting hole 43. The surface of the pin 44 is provided with a rubber layer 45. The upper end of the limiting block 42 is fixedly connected with a threaded rod 46. The upper end of the threaded rod 46 is fixedly connected with a crank 47. The surface of the threaded rod 46 is threadedly connected with a lifting block 48. The surface of the lifting block 48 is fixedly connected with two connecting rods 49. One end of the connecting rod 49 is fixedly connected to the lifting end of the lifting mechanism 5.

[0022] In this embodiment, the user rotates the crank handle 47, thereby causing the threaded rod 46 and the limiting block 42 to rotate, which causes the lifting block 48 to rise and fall on the surface of the threaded rod 46. Then, through the two connecting rods 49, the lifting ends of the two lifting mechanisms 5 are simultaneously raised and lowered. When the lifting height is appropriate, the user inserts the pin 44 into the hole opened on the surface of the limiting block 42 and into the inside of the limiting hole 43, thereby locking the rotation position of the limiting block 42. At the same time, the pin 44 is fastened to the inside of the limiting hole 43 by the rubber layer 45.

[0023] like Figure 3 and Figure 4 As shown, the lifting mechanism 5 includes a fixed sleeve 51, a sliding rod 52, a sliding block 53, and a ground wheel 54. The fixed sleeve 51 is fixedly connected to the end face of the mounting frame 3. The upper end of the fixed sleeve 51 is slidably connected to the sliding rod 52 that passes through it. The upper end of the sliding rod 52 is fixedly connected to the connecting rod 49. The lower end of the sliding rod 52 is fixedly connected to the sliding block 53. The sliding block 53 is slidably connected to the inner wall of the fixed sleeve 51. The surface of the sliding block 53 is rotatably connected to the ground wheel 54.

[0024] In this embodiment, when the connecting rod 49 rises or falls, it causes the sliding rod 52 to slide, which in turn causes the sliding block 53 to slide inside the fixed sleeve 51, thereby changing the distance between the ground wheel 54 and the mounting frame 3, thus allowing the height of the rice transplanter 1 to be adjusted.

[0025] like Figure 2As shown, the rice seedling cutter 1 includes a chassis 11, a cover plate 12, a transmission box 13, a drive pulley 14, a first rice seedling cutter assembly 15, a second rice seedling cutter assembly 16, a first driven pulley 17, and a second driven pulley 18. The cover plate 12 is mounted on the surface of the chassis 11, and the transmission box 13 is mounted on the surface of the cover plate 12. The drive pulley 14 is mounted on the output shaft end of the transmission box 13. The first rice seedling cutter assembly 15 and the second rice seedling cutter assembly 16 are rotatably connected in the middle of the chassis 11. The second driven pulley 18 is mounted on the shaft end of the second rice seedling cutter assembly 16, and the first driven pulley 17 is mounted on the shaft end of the first rice seedling cutter assembly 15. The first driven pulley 17 is connected to the second driven pulley 18 and the drive pulley 14 respectively via two transmission belts.

[0026] In this embodiment, when the seedling cutter 1 is working, the seedling cutter 1 is first connected to the vehicle body using the connecting frame 2. Then, the drive motor of the vehicle body drives the transmission box 13 to run. The transmission box 13 drives the drive pulley 14 to rotate using its output end. The drive pulley 14 drives the driven pulley 17 to rotate using the transmission belt, thereby driving the seedling cutter assembly 15 to rotate. At the same time, since the driven pulley 17 rotates, it drives the driven pulley 18 to rotate via the transmission belt, thereby driving the seedling cutter assembly 16 to rotate. Therefore, the seedling cutter of onions can be achieved through the seedling cutter assembly 15 and the seedling cutter assembly 16.

[0027] like Figure 2 As shown, the leveling mechanism 6 includes a bracket 61, an mounting strip 62, and a rubber baffle 63. The bracket 61 is fixedly connected to the surface of the fixing sleeve 51. The mounting strip 62 is installed on the surface of the bracket 61 by screws. The rubber baffle 63 is fixedly connected to the lower end face of the mounting strip 62.

[0028] In this embodiment, when the rice seedling cutter 1 is working, the rice seedling cutter 1 drives the leveling mechanism 6 to move. The leveling mechanism 6 can use the rubber baffle 63 to spread the broken leaves flat on the ground.

[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
