Description

Technical Field

[0001] The invention belongs to the technical field of seedling raising, and specifically relates to a deviation correction mechanism for a self-propelled rice seedling raising and tray placing machine. Background Art

[0002] A self-propelled rice seedling raising and tray placing machine is an agricultural machine that combines automated sowing technology and walking function, and is widely used in the seedling raising link of rice planting. It realizes functions such as automatic tray supply, sowing, soil covering, spraying, and output of seedling trays through mechanical means, and at the same time has the ability of autonomous movement, and can flexibly adapt to the operation requirements of different fields. With the development of agricultural modernization, the mechanization level in the process of rice planting has been continuously improved. In the rice seedling raising link, as an efficient and convenient agricultural machine, the self-propelled rice seedling raising and tray placing machine is widely used in the work of placing seedling trays; although the common self-propelled rice seedling raising and tray placing machines currently available can realize the basic function of placing seedling trays, they are prone to deviation during operation. This deviation problem is mainly manifested in that during the process of the machine moving forward, due to reasons such as uneven ground, soft soil, or unreasonable design of the machine's own structure, the walking path of the tray placing machine deviates from the predetermined track. Once deviation occurs, it will not only affect the neat arrangement of the seedling trays, but may also cause the distance between adjacent seedling trays not to meet the standard requirements, thus affecting subsequent sowing and management operations.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figures 1 to 10 As shown, the present invention provides a deviation correction mechanism for a self-propelled rice seedling raising swing plate machine, comprising a swing plate machine body 1, and also comprising: A guide assembly 2 is placed on the seedling raising ground, and the swing plate mechanical body 1 moves on the guide assembly 2; A sliding assembly 4, the sliding assembly 4 is installed on the outside of the swing plate mechanical body 1 through a limiting assembly 5; A stabilizing component 3, which is installed on both sides of the limiting component 5; The guide assembly 2 includes two main beams 25, and the side of the main beam 25 is fixedly provided with a first docking rod 26 at equal intervals. A first guide rail 21, a second guide rail 22, a third guide rail 23 and a fourth guide rail 24 are arranged at equal intervals between the two main beams 25, and docking blocks 27 are fixedly provided at both ends of the first guide rail 21, the second guide rail 22, the third guide rail 23 and the fourth guide rail 24 respectively. The first guide rail 21 , the second guide rail 22 , the third guide rail 23 and the fourth guide rail 24 are sleeved on the outside of the first docking rod 26 through the docking block 27 and installed between the two main beams 25 by means of nuts. The bottom of the first guide rail 21 is kept horizontal with the main beam 25 .

[0019] An annular groove matching the first guide rail 21 is provided in the middle of the outer portion of the driving wheel of the swing plate mechanical body 1, and a rubber pad is provided on the inner wall of the annular groove; The plate swinging machine body 1 moves along the first guide rail 21 and the second guide rail 22 through the driving wheel to swing the seedlings.

[0020] Two main beams 25 are placed at both ends of a seedling raising field or a seedling raising greenhouse, a first guide rail 21, a second guide rail 22, a third guide rail 23 and a fourth guide rail 24 are installed between the two main beams 25 via a docking block 27, a swing plate machine body 1 is placed on the first guide rail 21 and the second guide rail 22, the seedling raising plate is placed in the seedling raising field or the greenhouse in turn through the working movement of the swing plate machine body 1, the swing plate machine body 1 is limited and guided by the first guide rail 21 and the second guide rail 22 to make it move in a straight line, to avoid the swing plate machine body 1 deviating from the predetermined track during movement due to the uneven ground of the seedling raising field or the greenhouse, causing the seedling raising plate to deviate.

[0021] It is explained here that the distances among the first guide rail 21 , the second guide rail 22 , the third guide rail 23 and the fourth guide rail 24 can be adjusted according to the width of the swing plate machine body 1 and the width of the seedling raising plate.

[0022] like Figures 7 - 9 As shown, the limit assembly 5 includes a movable ring 52 fixedly mounted on the outside of the swing plate mechanical body 1, and a docking ring 53 is movably sleeved on the outside of the movable ring 52, and a docking plate 51 is fixedly mounted on the outside of the docking ring 53; The inner wall of the docking ring 53 is provided with circular grooves in an annular array, and the outer periphery of the movable ring 52 is fixed with a spring 55 in an annular array. One end of the spring 55 is provided with a limit ball 54, and the limit ball 54 is correspondingly engaged in the circular groove.

[0023] When the swing plate mechanical body 1 moves to the other end along the first guide rail 21 and the second guide rail 22, the swing plate mechanical body 1 is rotated 180 degrees with the docking ring 53 as the central axis. At this time, the swing plate mechanical body 1 can adjust the direction of the seedling raising plate.

[0024] like Figures 4 - 8 As shown, the sliding assembly 4 includes a rectangular frame 41, and two sides of the inner wall of the rectangular frame 41 are provided with sliding grooves 43 for the butt joint plate 51 to slide; The limit assembly 5 and the swing plate mechanical body 1 are located at one end of the rectangular frame 41, and the driving wheel of the swing plate mechanical body 1 and the first guide rail 21 and the second guide rail 22 are kept vertical; The limit assembly 5 and the swing plate mechanical body 1 slide to the other end of the rectangular frame 41, and the driving wheel of the swing plate mechanical body 1 and the second guide rail 22 and the third guide rail 23 remain vertical; The sliding assembly 4 further includes a cylinder 42 fixedly mounted on the four corners of the rectangular frame 41, a first clamping frame 44 is fixedly mounted on the output end of the cylinder 42, two first clamping frames 44 are connected by a second docking rod 45, and a second clamping block 46 having the same shape as the first clamping frame 44 is fixedly mounted in the middle of the second docking rod 45; When the driving wheel of the wobble plate mechanical body 1 is located on the first guide rail 21 and the second guide rail 22, two of the first clamping frames 44 and the first guide rail 21 remain vertical, the other two first clamping frames 44 and the third guide rail 23 remain vertical, and the second clamping block 46 and the second guide rail 22 remain vertical; When the swing plate mechanical body 1 and the sliding assembly 4 move to the other end of the first guide rail 21 and the second guide rail 22, the four cylinders 42 push the second clamping block 46, the second docking rod 45 and the first clamping frame 44 to move downward, two of the first clamping frames 44 are clamped on the first guide rail 21, and the other two first clamping frames 44 are clamped on the third guide rail 23, so as to prop up the swing plate mechanical body 1; The swing plate mechanical body 1 is pushed to make the docking plate 51 slide along the slide groove 43 to the other end of the rectangular frame 41 , and the driving wheel of the swing plate mechanical body 1 and the second guide rail 22 and the third guide rail 23 remain vertical.

[0025] The seedling raising plates are placed in the seedling raising field or greenhouse in sequence by moving the swing plate mechanical body 1 along the first guide rail 21 and the second guide rail 22. When the swing plate mechanical body 1 moves to the other end of the first guide rail 21 and the second guide rail 22, the cylinder 42 starts the output end to push the first clamping frame 44 and the second clamping block 46 downward, wherein two first clamping frames 44 are clamped at the top of the first guide rail 21, and the other two first clamping frames 44 are clamped at the top of the third guide rail 23, and the two second clamping blocks 46 are clamped at the top of the second guide rail 22. As the output end of the cylinder 42 is continuously pushed out, the swing plate mechanical body 1 is propped up to disengage the driving wheel from the contact with the first guide rail 21 and the second guide rail 22, so that the swing plate mechanical body 1 and the docking plate 51 can be pushed to slide along the slide groove 43 to the other end of the rectangular frame 41. At this time, the driving wheel of the swing plate mechanical body 1 and the second guide rail 22 and the third guide rail 23 remain vertical. At this time, the output end of the air cylinder 42 contracts reversely, and the driving wheels of the swing plate mechanical main body 1 gradually fall onto the second guide rail 22 and the third guide rail 23, while the first clamping frame 44 and the second clamping block 46 gradually disengage from the first guide rail 21, the second guide rail 22 and the third guide rail 23. Since the driving wheels of the swing plate mechanical main body 1 fall onto the second guide rail 22 and the third guide rail 23, at this time, the lifting and stabilizing assembly 3 pushes the rectangular frame 41 to keep two of the first clamping frames 44 vertical with the second guide rail 22, and the other two first clamping frames 44 vertical with the fourth guide rail 24. By repeating this process, the seedling trays can be placed into the greenhouse or the seedling nursery field in sequence, and at the same time, the first guide rail 21 can be removed and reused cyclically.

[0026] As Figures 8 - 10 shown, the stabilizing assembly 3 includes magnet blocks 31 fixedly installed on both sides of the rectangular frame 41. A guide rod 33 is movably sleeved on the magnet block 31. A first metal limit block 32 is fixedly installed at the top of the guide rod 33, and a second metal limit block 34 is fixedly installed at the bottom of the guide rod 33; When the swing plate mechanical main body 1 slides to the other end of the rectangular frame 41, the first metal limit block 32, the guide rod 33 and the second metal limit block 34 are pushed downward, and the guide rod 33 and the second metal limit block 34 are clamped to the outside of the rectangular frame 41.

[0027] The swing plate mechanical main body 1 is lifted by the sliding assembly 4, and the swing plate mechanical main body 1 and the limiting assembly 5 are pushed to slide along the sliding groove 43 to the other end of the rectangular frame 41. At this time, the first metal limit block 32, the guide rod 33 and the second metal limit block 34 are pushed downward. Since the guide rod 33 and the second metal limit block 34 are located outside the rectangular frame 41, the swing plate mechanical main body 1 and the limiting assembly 5 are fixed to the other end of the rectangular frame 41 through the stabilizing assembly 3, preventing the swing plate mechanical main body 1 and the limiting assembly 5 from moving reversely along the sliding groove 43.

[0028] The working principle and usage process of the present invention: Place the two main beams 25 at both ends of the seedling nursery field or the greenhouse. The first guide rail 21, the second guide rail 22, the third guide rail 23 and the fourth guide rail 24 are installed between the two main beams 25 through the docking blocks 27. The swing plate mechanical main body 1 is placed on the first guide rail 21 and the second guide rail 22. The seedling trays are placed into the seedling nursery field or the greenhouse in sequence through the operation of the swing plate mechanical main body 1. The first guide rail 21 and the second guide rail 22 limit and guide the swing plate mechanical main body 1 to move linearly, preventing the swing plate mechanical main body 1 from deviating from the predetermined track during the movement due to the uneven ground of the seedling nursery field or the greenhouse, resulting in the deviation of the seedling trays; The seedling raising plates are placed in the seedling raising field or greenhouse in sequence by moving the swing plate mechanical body 1 along the first guide rail 21 and the second guide rail 22. When the swing plate mechanical body 1 moves to the other end of the first guide rail 21 and the second guide rail 22, the cylinder 42 starts the output end to push the first clamping frame 44 and the second clamping block 46 downward, wherein two first clamping frames 44 are clamped at the top of the first guide rail 21, and the other two first clamping frames 44 are clamped at the top of the third guide rail 23, and the two second clamping blocks 46 are clamped at the top of the second guide rail 22. As the output end of the cylinder 42 continues to be pushed out, the swing plate mechanical body 1 is propped up to disengage the driving wheel from When the first guide rail 21 and the second guide rail 22 are in contact, the swing plate mechanical body 1 and the docking plate 51 can be pushed to slide along the slide groove 43 to the other end of the rectangular frame 41. At this time, the driving wheel of the swing plate mechanical body 1 and the second guide rail 22 and the third guide rail 23 remain vertical. At this time, the first metal limit block 32, the guide rod 33 and the second metal limit block 34 are pushed downward. The guide rod 33 and the second metal limit block 34 are located outside the rectangular frame 41, so that the swing plate mechanical body 1 and the limit assembly 5 are fixed to the other end of the rectangular frame 41 through the stabilizing assembly 3, so as to prevent the swing plate mechanical body 1 and the limit assembly 5 from moving in the opposite direction along the slide groove 43; At this time, the output end of the cylinder 42 contracts in the opposite direction, and the driving wheel of the swing plate mechanical body 1 gradually falls onto the second guide rail 22 and the third guide rail 23, while the first clamping frame 44 and the second clamping block 46 gradually separate from the first guide rail 21, the second guide rail 22 and the third guide rail 23. Since the driving wheel of the swing plate mechanical body 1 falls onto the second guide rail 22 and the third guide rail 23, the lifting stabilizing component 3 pushes the rectangular frame 41 to keep two of the first clamping frames 44 and the second guide rail 22 vertically, and the other two first clamping frames 44 and the fourth guide rail 24 vertically. In this reciprocating manner, the seedling trays can be placed in the greenhouse or the seedling field in sequence, and the first guide rail 21 can be removed for recycling.
