Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, and particularly to a seedling tray conveying mechanism. Background Art

[0002] The rice seedling tray raising and sowing is an important link in the factory production of seedlings. Developing a rice seedling tray raising and sowing machine that is compatible with the transplanting and planting machinery is an important guarantee for realizing the mechanization of rice planting. In order to improve agricultural production efficiency, intelligent rice seedling placing machines and greenhouse seedling raising combined operation machines have emerged in agricultural production.

[0003] In these intelligent mechanical devices, the conveying of the seedling tray is usually supported by a conveying line. For example, the Chinese patent document with the publication number CN210076006U discloses a turning type seedling tray conveying production line, which includes a frame. The turning conveying component is installed on the turning support. The turning support includes an arc-shaped bottom plate. A plurality of support legs are provided below the arc-shaped bottom plate. Side support plates are vertically provided on both the inner and outer sides of the arc-shaped bottom plate. A plurality of turning rollers are arranged in sequence along the arc direction of the arc-shaped bottom plate between the two side support plates. The conveying production line in this patent document can be combined by a plurality of linear conveying components and turning conveying components, and can realize the long-distance turning conveying of the seedling tray, and can avoid the situation of insufficient power.

[0004] However, when the turning type seedling tray conveying production line cooperates with the linear conveying component, its conveying plane is flush with the conveying plane of the linear conveying component, and its application scenario is relatively single. In the face of the complex terrain of the field, it is very difficult to ensure that the conveying planes of the linear conveying component and the turning type conveying component are flush. Moreover, the conveying path formed by the turning type conveying component and the linear conveying component is fixed and single, and can only carry out the conveying work along the established conveying path, and cannot adapt to the dynamic conveying path. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a seedling tray conveying mechanism, which solves the problem that the conveying path formed by the turning type conveying component and the linear conveying component of the seedling tray conveying mechanism in the prior art is fixed and single, and can only carry out the conveying work along the established conveying path, and cannot adapt to the dynamic conveying path.

[0006] To achieve the above purpose, the utility model provides a seedling tray conveying mechanism, which includes a linear conveying mechanism and a turning conveying mechanism. The turning conveying mechanism is movably arranged on the linear conveying mechanism. A transition mechanism is connected between the conveying plane of the linear conveying mechanism and the conveying plane of the turning conveying mechanism. Both the transition mechanism and the turning conveying mechanism are detachably connected to the linear conveying mechanism. The turning conveying mechanism and the transition mechanism can rotate and arrange the direction on the linear conveying mechanism.

[0007] Furthermore, the height of the conveying plane of the linear conveying mechanism relative to the ground is lower than that of the turning conveying mechanism relative to the ground. A traveling mechanism is provided at the bottom of the turning conveying mechanism, and the traveling mechanism drives the turning conveying mechanism to move along the conveying direction of the linear conveying mechanism.

[0008] Furthermore, the transition mechanism is provided with limiting wheels which are in contact with the linear conveying mechanism, and the transition mechanism can move along the conveying direction of the linear conveying mechanism through the limiting wheels.

[0009] Furthermore, the transition mechanism includes a head end, a tail end and a conveying part. The conveying part is located between the head end and the tail end. The head end is connected to the linear conveying mechanism, and the tail end is connected to the turning conveying mechanism; the limiting wheels are arranged at a position close to the head end.

[0010] Furthermore, an auxiliary mechanism is provided at the head end of the transition mechanism, and the auxiliary mechanism is used to assist the seedling tray to be conveyed from the head end to the conveying part; the auxiliary mechanism includes a power mechanism or a non-power mechanism.

[0011] Furthermore, the auxiliary mechanism includes end plates and a plurality of non-power rollers. The non-power rollers are arranged on the top surface of the end plates. The plurality of non-power rollers are arranged at intervals, and the radial direction of the non-power rollers is parallel to the conveying direction of the seedling tray.

[0012] Furthermore, the width of the free end of the end plate is smaller than the width of the end of the end plate close to the conveying part.

[0013] Furthermore, the auxiliary mechanism includes a support rod, and power rollers are arranged on both sides of the support rod, and the power rollers rotate synchronously.

[0014] Furthermore, the power rollers are driven by the driving mechanism of the conveying part.

[0028] Embodiment 1

[0029] Refer to Figures 1 - 6, this embodiment provides a seedling tray conveying mechanism, including a linear conveying mechanism 1 and a turning conveying mechanism 2. The turning conveying mechanism 2 is movably arranged on the linear conveying mechanism 1. There is a transition mechanism 3 connected between the conveying planes of the linear conveying mechanism 1 and the turning conveying mechanism 2. The transition mechanism 3 can transfer the seedling trays on the linear conveying mechanism 1 to the turning conveying mechanism 2. Both the transition mechanism 3 and the turning conveying mechanism 2 are detachably connected to the linear conveying mechanism 1, and the turning conveying mechanism 2 and the transition mechanism 3 can rotate their arrangement directions on the linear conveying mechanism 1. Therefore, the transition mechanism 3 and the turning conveying mechanism 2 can move in the front and rear directions of the linear conveying mechanism 1, so that the work of conveying seedling trays can be carried out in two directions, and they can move back and forth at both ends of the paddy field, improving the efficiency of seedling tray conveying and adapting to the dynamic conveying path. Moreover, compared with the prior art, the device of this embodiment can adjust the conveying path by rotating the arrangement directions of the turning conveying mechanism 2 and the transition mechanism 3 on the linear conveying mechanism 1, and the conveying path is more diverse.

[0030] Specifically, referring to Figure 1 , in this embodiment, the height of the conveying plane of the linear conveying mechanism 1 relative to the ground is lower than the height of the conveying plane of the turning conveying mechanism 2 relative to the ground. The height difference between the two forms two conveying spaces for the turning conveying mechanism 2 and the linear conveying mechanism 1, and the two conveying spaces can function independently without interference. A traveling mechanism 5 is arranged at the bottom of the turning conveying mechanism 2, and the traveling mechanism 5 drives the turning conveying mechanism 2 to move along the conveying direction of the linear conveying mechanism 1. The traveling mechanism 5 mainly functions to drive the turning conveying mechanism 2. The traveling mechanism 5 includes a frame, and a plurality of traveling wheels are arranged on the frame. The traveling wheels are in contact with the linear conveying mechanism 1. A motor is arranged on the frame, and the motor drives the traveling wheels to rotate through a transmission structure, so as to move the turning conveying mechanism 2 on the linear conveying mechanism 1.

[0031] When the turning conveying mechanism 2 moves, it will also drive the transition mechanism 3 to move. To prevent the transition mechanism 3 from deviating from the moving track on the linear conveying mechanism 1, further, as Figure 2 and Figure 3As shown in the figure, the transition mechanism 3 is provided with a limit wheel 4. The limit wheel 4 contacts the linear conveying mechanism 1. The transition mechanism 3 can move along the conveying direction of the linear conveying mechanism 1 through the limit wheel 4. The limit wheel 4 can not only play a limiting role but also play a guiding role. Specifically, the transition mechanism 3 includes a head end 301, a tail end 302, and a conveying part 303. The conveying part 303 is located between the head end 301 and the tail end 302. The head end 301 is connected to the linear conveying mechanism 1, and the tail end 302 is connected to the turning conveying mechanism 2; the limit wheel 4 is arranged at a position close to the head end 301. The conveying part 303 conveys the seedling tray linearly from the head end 301 to the tail end 302, or conveys the seedling tray linearly from the tail end 302 to the position of the head end 301. The conveying part 303 includes a driving motor, a driving wheel 3031, a driven wheel 3032, and a conveyor belt 3033. The driving wheel 3031 is arranged at a position close to the tail end 302, and the driven wheel 3032 is arranged at a position close to the head end 301. The conveyor belt 3033 is sleeved on the driving wheel 3031 and the driven wheel 3032.

[0032] The main function of the transition mechanism 3 is to complete the transition of the seedling tray between the linear conveying mechanism 1 and the turning conveying mechanism 2, and it is necessary to have good transition smoothness for the seedling tray. Please continue to refer to Figure 2 and Figure 3 In this embodiment, an auxiliary mechanism is provided at the head end 301 of the transition mechanism 3. The auxiliary mechanism is used to assist the seedling tray to be conveyed from the head end 301 to the conveying part 303. Among them, the auxiliary mechanism is a non-powered mechanism. Specifically, the auxiliary mechanism includes an end plate 304 and a number of non-powered rollers 305. The non-powered rollers 305 are arranged on the top surface of the end plate 304. The number of non-powered rollers 305 is arranged at intervals, and the radial direction of the non-powered rollers 305 is parallel to the conveying direction of the seedling tray. When the seedling tray is conveyed from the linear conveying mechanism 1 to the turning conveying mechanism 2, the non-powered rollers 305 can roll along the roller shaft by themselves, which can reduce the resistance during the conveying process of the seedling tray and is beneficial to improving the conveying efficiency of the seedling tray.

[0033] It should be noted that, in order to facilitate the transition mechanism 3 to smoothly connect the seedling tray from the linear conveying mechanism 1 to the turning conveying mechanism 2, the width of the free end of the end plate 304 is smaller than the width of the end of the end plate 304 close to the conveying part 303. The smaller free end reduces the contact area between the end plate 304 and the seedling tray, which is beneficial to the free end to "shovel" up the seedling tray and facilitate the seedling tray to enter the transition mechanism 3 and thus flow into the next mechanism. Furthermore, the transition mechanism 3 is also provided with a guiding device 308. The guiding device 308 guides the seedling tray from the head end 301 into the conveying part 303. In this embodiment, the guiding device 308 is a guiding plate arranged along the conveying direction of the conveying part 303. The side of the guiding plate close to the end plate 304 has a slope, and the seedling tray can enter the conveying part 303 by means of the slope.

[0034] Embodiment 2

[0035] Based on the first embodiment, different from the first embodiment, in this embodiment, the auxiliary mechanism is a powered mechanism. As Figure 4 , Figure 5 and Figure 6 shown, the auxiliary mechanism includes a support rod 306. Power rollers 307 are arranged on both sides of the support rod 306 and rotate synchronously. The power rollers 307 are driven by the drive mechanism of the conveying part 303. Specifically, the power rollers 307 are connected to the driving wheel 3031 through a conveyor belt 3033. When the driving wheel 3031 rotates, the power rollers 307 are driven to rotate through the conveyor belt 3033. The rotation of the power rollers 307 can provide power for the movement of the seedling tray, which is beneficial to improving the efficiency of seedling tray transfer. Further, the end of the support rod 306 is provided with a downward slope, which also plays the role of "shoveling" up the seedling tray.

[0036] Slightly different from the first embodiment, the guiding device 308 is also a guiding plate arranged along the conveying direction of the conveying part 303. The two guiding plates are arranged opposite to each other on both sides of the conveying part 303. An opening is formed at the position where the two guiding plates are close to the support rod 306. Chamfers are respectively arranged at the ends of the two guiding plates. The chamfers make the distance between the openings larger, so that it is beneficial for the seedling tray to enter the conveying part 303 from the opening, and the opposite chamfers play a guiding role for the seedling tray.

[0037] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "middle", "upper", "lower", "left", "right", "inner", "outer", "top", "bottom", "side", "vertical", "horizontal", etc. is based on the orientation or positional relationship shown in the drawings.
