Description

Technical Field

[0001] This utility model belongs to the field of seedling technology, specifically relating to a movable tray transfer and stacking vehicle suitable for mobile seedling beds. Background Technology

[0002] Mobile seedbeds are a common type of specialized equipment used for seedling cultivation and growth. They offer advantages such as ground isolation, reduced water accumulation, space saving, fewer pests and diseases, and a height suitable for manual operation. Currently, automated seedling cultivation using tray seedling machines is quite common in greenhouse seedling production. After seedling cultivation, the trays need to be transferred to the seedbeds. This transfer process utilizes stacking carts. The trays are first stacked on the cart, which is then manually pushed and pulled to the seedbed.

[0003] However, due to the bumpy road conditions that may occur during the transportation of the stacking vehicle, the seedling trays may be squeezed by gravity or the substrate may fall off. At the same time, the staff need to lift the seedling trays one by one from top to bottom and place them on the seedling bed, which is a lot of work and requires a lot of physical strength. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a movable tray transfer and stacking vehicle suitable for mobile seedling beds. By using a limiting rod and a support rod of the vehicle frame to surround the tray and the seedling trays on it, the vehicle can effectively prevent the seedling trays on the tray from tipping over due to bumps during transportation, thus stabilizing and protecting the seedling trays.

[0005] The specific technical solution adopted in this utility model is as follows:

[0006] A mobile seedling tray transfer and stacking vehicle suitable for mobile seedling beds includes a frame and a tray. Multiple sets of seedling trays are stacked on the tray. A limit bar is provided on the frame along the vertical direction. The limit bar and the support rod of the frame along the vertical direction are located on the front and rear sides of the tray, respectively. The limit bar and the support rod of the frame together surround the tray and form a limiting channel. The frame is also provided with a lifting mechanism. The tray has the freedom of lifting and lowering by means of the lifting mechanism. The first seedling tray located at the top of the tray is lifted above the limiting channel by means of the lifting mechanism and slides horizontally towards the limit bar to the area to be transferred to form unloading.

[0007] The bottom of the seedling tray is symmetrically provided with sliding grooves on the left and right sides, and the sliding grooves are arranged along the unloading direction of the seedling tray. The top of the seedling tray is symmetrically provided with sliding rails that cooperate with the sliding grooves on the left and right sides, and the sliding groove of the upper seedling tray and the sliding rail of the lower seedling tray form a sliding fit.

[0008] The lifting mechanism includes a guide rod, a traction rope, a fixed pulley, and a tension spring. The guide rod is symmetrically arranged on both sides of the frame in a vertical direction. One end of the traction rope is fixedly connected to the tray, and the other end of the traction rope passes through the fixed pulley at the top of the frame and is connected to the tension spring at the bottom of the frame. The two sides of the tray are respectively connected to the guide rod by means of sliding sleeves to form a sliding fit. The tray has the freedom to slide up and down along the guide rod by means of the tension of the tension spring and the weight of the seedling tray. The bottom height of the primary seedling tray on the tray is always limited to the top height of the height limit rod by means of the lifting mechanism.

[0009] The vehicle frame is also provided with a limiting base, which is fixedly located in the lower half of the vehicle frame, and the tray has the freedom to move up and down above the limiting base.

[0010] The tray is symmetrically equipped with baffles on its left and right sides, and the seedling trays on the tray are limited by the clamping of the baffles and the limiting rods.

[0011] The guide rod is also provided with a rotating sleeve. Limiting blocks that are fixedly connected to the guide rod are respectively provided on the upper and lower sides of the rotating sleeve. A pressure rod is connected to the rotating sleeve. The pressure rod has the freedom to rotate in the horizontal direction with the help of the rotating sleeve. The pressure rod is located above the primary seedling tray and presses down on the primary seedling tray.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model adds a limiting rod and a lifting mechanism. The limiting rod and the support rod of the frame work together to surround the pallet and the seedling trays on the pallet, which can effectively prevent the seedling trays on the pallet from tipping over due to bumps during transportation, and play a role in stabilizing and protecting the seedling trays.

[0014] The lifting structure in this invention is a non-powered lifting structure. Utilizing the resilience of the tension spring, the topmost seedling tray on the tray remains in the same position. Workers simply need to push the first-level seedling tray towards the seedling bed to place it on the bed. The next-level seedling tray rises above the limit channel under the action of the lifting mechanism, forming a new first-level seedling tray. This unloading operation is repeated, enabling convenient unloading of seedling trays one by one through cyclical operation, reducing the labor intensity of workers.

[0015] 2. This utility model is equipped with a pressure bar. By pressing the seedling tray with the pressure bar, the top seedling tray on the tray is always in the same position. Due to the setting of the limiting block, the rotating sleeve cannot move up and down, and only has the freedom of horizontal rotation. Therefore, the height of the pressure bar is fixed. When loading, the pressure bar can be rotated to both sides to avoid the material. After loading is completed, the pressure bar can be rotated back and the first seedling tray can be pressed.

[0016] In addition, the pressure bar can also press down on the seedling tray to fix it in place. The pressure bar, the limiting channel, and the tray together surround the seedling tray to prevent the seedling tray from being squeezed by gravity or the substrate from falling off due to the undulation of the tray on bumpy roads.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0025] Specific embodiments, such as Figure 1-6 As shown, this utility model provides a movable tray transfer and stacking vehicle suitable for mobile seedling beds, including a frame 1 and a tray 2. Multiple sets of seedling trays 3 are stacked on the tray 2. A limit rod 4 is provided on the frame 1 along the vertical direction. The limit rod 4 and the support rod 5 along the vertical direction of the frame 1 are located on the front and rear sides of the tray 2, respectively. The limit rod 4 and the support rod 5 of the frame 1 together surround the tray 2 and form a limiting channel. The frame 1 is also provided with a lifting mechanism. The tray 2 has the freedom of lifting and lowering by means of the lifting mechanism. The first seedling tray 3 located at the top of the tray 2 is raised to the limit channel by means of the lifting mechanism and slides horizontally towards the limit rod 4 to the area to be transferred to form unloading.

[0026] After automating seedling cultivation using a plug tray seedling machine, the plug trays need to be transferred to the seedling bed. This transfer process involves using a stacking cart. The seedling trays (3) are first stacked on the cart, and then the cart is manually pushed and pulled to the seedling bed. However, due to potential road bumps during transport, the seedling trays (3) are easily subjected to pressure or substrate loss. Furthermore, when disassembling the seedling trays (3), workers must lift them one by one from top to bottom and place them on the seedling bed, which is labor-intensive and physically demanding.

[0027] Therefore, this utility model adds a limiting rod 4 and a lifting mechanism. First, the limiting rod 4 and the support rod 5 of the frame 1 work together to surround the tray 2 and the seedling tray 3 on the tray 2, which can effectively prevent the seedling tray 3 on the tray 2 from tipping over due to bumps during transportation, and play a role in stabilizing and protecting the seedling tray 3.

[0028] When the stacking vehicle delivers the seedling tray 3 to the side of the seedling bed, first align one side of the stacking vehicle's limiting rod 4 with the edge of the seedling bed. As the topmost seedling tray 3 of the tray 2 rises above the limiting channel under the action of the lifting mechanism, at this time... Figure 3 As shown, the worker only needs to push the primary seedling tray 3 towards the seedling bed to place it on the seedling bed. The seedling trays 3 below the primary seedling tray 3 will not disengage from the limiting channel due to the obstruction of the limiting rod 4. Once the primary seedling tray 3 is completely disengaged from the limiting channel, the next-level seedling tray 3 will rise above the limiting channel under the action of the lifting mechanism, forming a new primary seedling tray 3. Figure 4 As shown, the above unloading operation can be repeated. Through cyclical operation, the seedling tray 3 can be unloaded one by one in a convenient way, reducing the labor intensity of the staff.

[0029] like Figure 5-6 As shown, the bottom left and right sides of the seedling tray 3 are symmetrically provided with sliding grooves 6, which are arranged along the unloading direction of the seedling tray 3. The top left and right sides of the seedling tray 3 are symmetrically provided with sliding rails 7 that cooperate with the sliding grooves 6. The sliding grooves 6 of the upper seedling tray 3 and the sliding rails 7 of the lower seedling tray 3 form a sliding fit. The setting of the sliding grooves 6 and sliding rails 7 is, on the one hand, to facilitate the workers to push the seedling tray 3, so as to easily unload the seedlings; on the other hand, the cooperation of the sliding grooves 6 and sliding rails 7 plays a certain limiting role. Since the limiting rod 4 and the support rod 5 are located in the front and rear directions of the seedling tray 3 respectively, and there is no obstruction in the left and right directions of the seedling tray 3, the sliding grooves 6 and sliding rails 7 can prevent the stacked upper and lower seedling trays 3 from being relatively displaced in the left and right directions.

[0030] like Figure 1-4As shown, the lifting mechanism includes a guide rod 8, a traction rope 9, a fixed pulley 10, and a tension spring 11. The guide rod 8 is symmetrically arranged on both sides of the frame 1 in a vertical direction. One end of the traction rope 9 is fixedly connected to the tray 2, and the other end of the traction rope 9 passes through the fixed pulley 10 at the top of the frame 1 and is connected to the tension spring 11 at the bottom of the frame 1. The two sides of the tray 2 are respectively connected to the guide rod 8 by means of the sliding sleeve 12. The tray 2 has the freedom to slide up and down along the guide rod 8 by means of the tension of the tension spring 11 and the weight of the seedling tray 3. The bottom height of the primary seedling tray 3 on the tray 2 is always limited to the top height of the height limit rod 4 by means of the lifting mechanism.

[0031] The lifting mechanism in this invention is a non-powered lifting mechanism. Since there are no motors, cylinders, or other power equipment, the overall weight of the stacking cart is greatly reduced, making it easier for staff to push and move the stacking cart.

[0032] The lifting structure, with the help of the elasticity of the tension spring 11, ensures that the uppermost seedling tray 3 on the tray 2 remains in the same position. When multiple seedling trays 3 are placed on the tray 2, the first-level seedling tray 3 is located at A0 above the limiting channel. When the first-level seedling tray 3 is removed, the weight on the tray 2 decreases, and the overall weight of the tray 2 and the seedling trays 3 is less than the tension provided by the tension spring 11. Therefore, the tension spring 11 contracts a certain distance, and under the action of the fixed pulley 10 and the traction rope 9, the tray 2 rises one unit height. At this time, the next-level seedling tray 3 is located at A0, and so on. The uppermost seedling tray 3 on the tray 2 remains in the same position, thus allowing the uppermost seedling tray 3 to be pushed to unload the seedling trays one by one.

[0033] like Figure 1 As shown, the frame 1 is also equipped with a limiting base 13, which is fixedly located in the lower half of the frame 1. The tray 2 has the freedom to move up and down above the limiting base 13. To prevent the total weight of the tray 2 and the seedling tray 3 on the tray 2 from exceeding the maximum tensile force provided by the tension spring 11, the present invention also provides a limiting base 13. When the bottom of the tray 2 contacts the limiting base 13, the limiting base 13 will provide support, preventing the tensile force provided by the tension spring 11 from continuing to increase, thereby reminding the staff that the maximum load capacity has been reached when stacking the vehicle, and avoiding damage to the tension spring 11.

[0034] As shown in 1-4, baffles 14 are symmetrically arranged on the left and right sides of the tray 2. The seedling trays 3 on the tray 2 are limited by the clamping of the baffles 14 and the limiting rods 4. Since the slide grooves 6 and slide rails 7 can prevent the stacked seedling trays 3 from being relatively displaced in the left and right directions, it is only necessary to limit the bottom seedling tray 3 in the left and right directions. The baffles 14, the limiting rods 4 and the support rods 5 together surround the bottom seedling tray 3, so that the bottom of the stacked seedling trays 3 will not shake, thereby increasing the stability of the seedling trays 3 on the stacking vehicle.

[0035] like Figure 1-4 As shown, a rotating sleeve 15 is also provided on the guide rod 8. Limiting blocks 16, which are fixedly connected to the guide rod 8, are respectively provided on the upper and lower sides of the rotating sleeve 15. A pressure rod 17 is connected to the rotating sleeve 15. The pressure rod 17 has the freedom to rotate horizontally with the help of the rotating sleeve 15. The pressure rod 17 is located above the primary seedling tray 3 and presses down on the primary seedling tray 3. In order to ensure that the uppermost seedling tray 3 on the tray 2 is always in the same position, this utility model also provides a pressure rod 17. By pressing the seedling tray 3 with the pressure rod 17, it is ensured that the uppermost seedling tray 3 on the tray 2 is always in the same position. Due to the setting of the limiting blocks 16, the rotating sleeve 15 cannot move up and down, and only has the freedom to rotate horizontally. Therefore, the height of the pressure rod 17 is fixed. When loading, the pressure rod 17 can be rotated to both sides to avoid the material. After loading is completed, the pressure rod 17 can be rotated back and pressed down on the primary seedling tray 3.

[0036] In addition, the pressure bar 17 can also press down on the seedling tray 3 to fix it. The pressure bar 17, together with the limiting channel and the tray 2, surrounds the seedling tray 3 to prevent the seedling tray 3 from being squeezed by gravity or the substrate from falling off due to the undulation of the road.
