Description

Technical Field

[0001] The utility model belongs to the technical field of rice planting, and in particular relates to a rice seedling transport device. Background Art

[0002] Rice is a type of herbaceous rice and is also the most important and oldest type of food in the genus Oryza. Rice planting techniques include rice fields and transplanting. During the rice planting process, the rice seedlings of appropriate age need to be transported to the fields for transplanting and planting. Since it is time-consuming and laborious to manually carry the rice seedlings to the fields and requires a lot of labor, a transfer device is needed to help transport the rice seedlings.

[0003] In order to ensure the survival of the rice seedlings as much as possible during the transportation of the rice seedlings, it is necessary to replenish the rice seedlings with water. The existing rice seedling transfer device often sprays water manually when spraying the rice seedlings, or sprays water through a water spray cover located just above the transfer plate, such as the patent with authorization publication number CN217136043U. Since it is often necessary to transport a large number of rice seedlings at a time in actual use, most of the transfer plates are arranged vertically in the transfer box, and it is difficult to spray water evenly by manual spraying. If a water spray cover is set just above each layer of the transfer plate, the cost is high, and more water spray covers will also occupy the valuable space between adjacent transfer plates.

[0004] Therefore, we propose a rice seedling transport device to solve the above problems. Utility Model Content

A first dial and a second dial are respectively and coaxially fixedly arranged on the sides of the first gear and the second gear. And the sheave cooperates with the first dial and the second dial at different times during a rotation period.

[0010] Preferably, a plurality of U-shaped placement racks are vertically and arrayedly arranged at the upper ends of both side walls of the box body.

Specific implementation mode

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0027] Referring to Figures 1-3 , a rice seedling transfer device includes a box body 1 with one side open. A box door can be hinged at the open part of the box body 1 to provide the airtightness inside the box body 1 and avoid external interference with the rice seedlings inside. A plurality of placing trays 2 are vertically arranged inside the box body 1. Drainage holes can be opened on the bottom surface of the placing tray 2 to avoid excessive water and long-term stay in the placing tray 2, which may affect the rice seedlings. Water spray assemblies are slidably arranged up and down on both inner side walls of the box body 1, and driving assemblies for driving the two water spray assemblies to lift are respectively arranged on both sides inside the box body 1.

[0028] Referring to Figures 2-4, on both sides of the box body 1, two opposite U-shaped slide rails 3 are fixedly provided. The water spraying assembly includes a U-shaped sliding plate 4 slidably connected between two slide rails 3 on the same side. A water spraying pipe 5 is rotatably connected between the two ends of the sliding plate 4. A water tank can be fixedly installed at the bottom inside the box body 1, and a water pump is installed in the water tank. The water outlet of the water pump is connected to a bifurcated connecting pipe, and the connecting pipe passes through the sliding plate 4 and is connected to the two water spraying pipes 5, so as to realize the water spraying of the water spraying pipe 5. On the side of the water spraying pipe 5 facing the placing plate 2, a plurality of water spraying nozzles should be arranged in an array, so as to cover the placing plate 2 as much as possible and improve the water spraying effect. A cavity 6 is opened in the side wall at one end of the sliding plate 4, and a reciprocating assembly for driving the water spraying pipe 5 to rotate reciprocally by relying on the up and down movement of the sliding plate 4 is arranged in the cavity 6.

[0029] An opening communicating with the outside of the sliding plate 4 is provided on one side of the cavity 6. A toothed plate 7 is fixedly connected to the side wall of the slide rail 3 facing the opening. A through groove for the toothed plate 7 to pass through is opened at one end of the sliding plate 4, and the opening is located in the through groove. Such a setting can ensure the contact surface between the two ends of the sliding plate 4 and the slide rail 3, thereby improving the stability of the up and down movement of the sliding plate 4. The reciprocating assembly includes a sheave 8 fixedly sleeved on one end of the water spraying pipe 5 extending into the cavity 6. A first gear 9 and a second gear 10 are rotatably connected to the side wall of the cavity 6. The first gear 9 and the second gear 10 are meshed with each other. One side of the second gear 10 extends to the outside of the opening and is meshed with the toothed plate 7. A first dial 11 and a second dial 12 are respectively coaxially fixedly provided on the sides of the first gear 9 and the second gear 10, and the sheave 8 cooperates with the first dial 11 and the second dial 12 at different times in a rotation cycle.

[0030] When the rice seedling transfer device is in use, the rice seedlings are placed in the placing plate 2. When the rice seedlings need to be replenished with water, the water spraying assembly and the driving assembly are turned on. At this time, the water spraying pipe 5 sprays water on the rice seedlings in the placing plate 2. At the same time, the driving assembly drives the sliding plate 4 to move up and down. The second gear 10 in the sliding plate 4 cooperates with the toothed plate 7 in the slide rail 3, and the second gear 10 rotates accordingly. The second gear 10 meshes with the first gear 9 and rotates synchronously. The first dial 11 and the second dial 12 drive the sheave 8 to rotate in turn in the reverse direction, and the water spraying pipe 5 rotates following the sheave 8 and realizes intermittent reciprocating rotation water spraying.

[0031] Refer to Figures 1-3 , on the upper ends of both side walls of the box body 1, a plurality of U-shaped placing frames 13 are vertically arranged in an array. The two ends of the placing plate 2 are respectively placed on two placing frames 13 of the same height. The two ends and the side surface of the placing plate 2 can be attached to the placing frame 13, so that the placing of the placing plate 2 can be more stable. The slide rail 3 and the driving assembly are both located inside the placing frame 13, so as to avoid the interference of the driving assembly and the water spraying assembly on the placing plate 2.

[0032] Refer to Figures 5-6, the driving assembly includes a vertical lead screw 14 rotatably arranged on the side wall of the box body 1. A hole for the lead screw 14 to pass through is formed in the middle of the sliding plate 4. A slider 15 is threadedly sleeved on the lead screw 14, and the slider 15 is fixedly connected to the sliding plate 4. A synchronous assembly for synchronizing the rotation of the two lead screws 14 is provided on the top of the box body 1. A mounting box 16 is fixedly connected to the top surface of the box body 1. The tops of the two lead screws 14 both extend into the mounting box 16. The synchronous assembly includes a sprocket 17 located in the mounting box 16 and fixedly sleeved on the top of the lead screw 14. A chain 18 for synchronous rotation is sleeved between the two sprockets 17. A motor for driving one of the lead screws 14 to rotate is fixedly installed on the top surface of the mounting box 16. Through the cooperation of the chain 18 and the sprocket 17, the synchronous rotation of the two lead screws 14 is achieved. The lead screw 14 and the slider 15 should use a ball screw combination to reduce friction, and the self-locking of the lead screw 14 is achieved through the motor.

[0033] Referring to Figure 4 , the number of radial grooves 19 on the Geneva wheel 8 is four. A cylindrical pin 20 is provided on both the first dial 11 and the second dial 12. Through the cooperation of the cylindrical pin 20 and the radial groove 19, the rotation of the Geneva wheel 8 is driven. A concave locking arc 21 is provided between two radial grooves 19 of the Geneva wheel 8. A convex locking arc 22 for cooperating with the concave locking arc 21 is provided on the first dial 11, and the radian of the convex locking arc 22 is 1 / 2π.

[0034] The number of radial grooves 19 can be four or six. When the number of radial grooves 19 is four, the radian of the convex locking arc 22 is 1 / 2π, and the rotation range of the Geneva wheel 8 is 90°. When the number of radial grooves 19 is six, convex locking arcs 22 with a radian of 1 / 3π can be provided on both the first dial 11 and the second dial 12, and the rotation range of the Geneva wheel 8 is 60°. Each of the two schemes has its own advantages and disadvantages. The former advantage is that the rotation angle of the Geneva wheel 8 and the water spray pipe 5 is larger, which can better cover the rice seedlings, but only one convex locking arc 22 can be set, so the Geneva wheel 8 will stay at the initial position for more time, which may cause uneven spraying. The latter advantage is that two convex locking arcs 22 can be set, and the Geneva wheel 8 stays at the two extreme values of the rotation range for the same time, and the spraying is more uniform, but the rotation range is smaller. Considering that the water spray pipes 5 on both sides can cooperate with each other, the above-mentioned disadvantages have less impact, and the scheme with four radial grooves 19 has a lower cost, so the scheme with four radial grooves 19 is selected for description.

[0035] Referring to Figure 4 and Figures 7-9, when the sliding plate 4 moves, one of the cylindrical pins 20 first drives the grooved pulley 8 to rotate 90°. When this cylindrical pin 20 disengages from the radial groove 19, the other cylindrical pin 20 simultaneously enters the radial groove 19 and drives the grooved pulley 8 to rotate reversely by 90°. When this cylindrical pin 20 disengages from the radial groove 19, the convex locking arc 22 cooperates with the concave locking arc 21 to lock the grooved pulley 8 until the first cylindrical pin 20 re-enters the radial groove 19, and the convex locking arc 22 just disengages from the concave locking arc 21.

[0036] As described above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
