Description

Technical Field

[0001] This utility model relates to the field of crop planting technology, specifically to an easily adjustable harvesting track for agricultural greenhouses. Background Technology

[0002] In current agricultural greenhouse harvesting operations, there are many problems affecting harvesting efficiency and convenience, which to some extent restrict the development of agricultural production. These problems are as follows:

[0003] Deficiencies of existing technology

[0004] Height Adaptability Issues: Traditional agricultural greenhouse harvesting equipment is mostly designed with a fixed height, making it impossible to adjust in real time according to the growth height of crops and changes in the weight of produce within the collection container. This forces workers to frequently adjust their posture or use additional tools to accommodate crops of varying heights during harvesting, increasing labor intensity and reducing harvesting efficiency. Furthermore, the inability to dynamically match the crop's growth height can easily lead to missed harvests or damage to crops.

[0005] Interruption of harvesting operations: Existing harvesting and collection devices usually only have a single-layer collection box. When the collection box is full, the harvesting operation needs to be paused to replace the collection box. This not only wastes time, but also affects the continuity of harvesting and reduces the overall harvesting efficiency.

[0006] Lack of flexibility and adaptability: Different types of crops vary significantly in weight; for example, strawberries are relatively light, while tomatoes are relatively heavy. However, existing harvesting equipment often cannot flexibly adjust its load-bearing capacity, making it difficult to simultaneously adapt to multiple crops of different weights. Furthermore, the loading and unloading process of the collection boxes is cumbersome, requiring considerable time and manpower, thus increasing production costs. Utility Model Content

[0007] The purpose of this invention is to provide an easily adjustable agricultural greenhouse harvesting track to solve the problems mentioned in the background art.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0009] An easily adjustable agricultural greenhouse harvesting track includes a slide rail and a lifting moving platform, wherein a lifting and collecting component is provided at one end of the lifting moving platform near the top.

[0010] The lifting and collecting assembly includes a lifting and placing frame one and a lifting and placing frame two. The lifting and placing frame two is fixedly connected to the top of the lifting and placing frame one by a connecting rod. Collection boxes are snapped into the inner walls of both the lifting and placing frame one and the lifting and placing frame two.

[0011] The top of the lifting and placing frame is fixedly connected to a slider. The top of the slider has a sliding hole. A guide plate is slidably connected to the outer wall of the slider. A guide rod is slidably connected to the inner wall of the sliding hole. A return spring is sleeved on the outer wall of the guide rod. A rod nut is threaded to the top of the guide rod.

[0012] A further improvement of this utility model is that: the side of the guide plate is provided with a guide groove for adapting to the slider, and the inner wall of the guide groove is slidably connected to the outer wall of the slider.

[0013] A further improvement of this utility model is that the top end of the reset spring overlaps with the bottom surface of the slider, and the bottom end of the guide rod is fixedly connected to the side of the guide plate by a mounting block.

[0014] A further improvement of this utility model is that a support frame is fixedly connected to the side of the lifting platform, and a side-mounted collection box is snapped into the inner wall of the support frame.

[0015] A further improvement of this utility model is that the outer wall of the lifting and placing frame is slidably connected to the inner wall of the guide plate.

[0016] A further improvement of this utility model is that: a lifting handle is fixedly connected to the top of the collection box, and a closed door is provided on the back of the lifting platform.

[0017] A further improvement of this utility model is that a material discharge trough is provided on the side of the lifting and moving platform near the lifting and collecting component.

[0018] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0019] 1. This utility model provides an easily adjustable agricultural greenhouse harvesting track. The gravity-adaptive height adjustment function allows the lifting and placing frame to descend as the weight of the agricultural products in the collection box increases, keeping the crop growth point at an appropriate height with the feeding trough. This achieves dynamic matching between the harvesting action and the crop growth height, greatly improving harvesting efficiency.

[0020] 2. This utility model provides an easily adjustable agricultural greenhouse harvesting track with a double-layer collection box design. When the collection box of the first lifting and placing frame is full, the second lifting and placing frame can be lowered in time to enter the working state. The lower collection box can be replaced at the same time, avoiding interruption of the harvesting operation and ensuring the continuity of the harvesting work.

[0021] 3. This utility model provides an easily adjustable agricultural greenhouse harvesting track. Its modular design gives the system high flexibility. By rotating the sliding nut and replacing the return spring with one of different elastic coefficients, the system's load-bearing capacity can be adjusted to accommodate the harvesting needs of crops of varying weights. Furthermore, the collection box can be easily installed and removed using a lifting handle and a closing door, further enhancing the system's applicability and ease of operation.

[0028] The present invention will be further described in detail below with reference to embodiments:

[0029] Example 1

[0030] like Figure 1-4 As shown, this utility model provides an easily adjustable agricultural greenhouse harvesting track, including a slide rail 1 and a lifting moving platform 2, with a lifting collection component 6 provided at one end of the lifting moving platform 2 near the top.

[0031] The lifting collection assembly 6 includes a lifting placement frame 13 and a lifting placement frame 2 15. The lifting placement frame 2 15 is fixedly connected to the top of the lifting placement frame 13 via a connecting rod. Collection boxes 16 are snapped into the inner walls of both the lifting placement frame 13 and the lifting placement frame 2 15.

[0032] A slider 14 is fixedly connected to the top of the lifting and placing frame 13. A sliding hole 17 is opened on the top of the slider 14. A guide plate 8 is slidably connected to the outer wall of the slider 14. A guide rod 10 is slidably connected to the inner wall of the sliding hole 17. A return spring 12 is sleeved on the outer wall of the guide rod 10. A rod nut 11 is threadedly connected to the top of the guide rod 10.

[0033] Example 2

[0034] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the side of the guide plate 8 is provided with a guide groove 9 for adapting to the slider 14, and the inner wall of the guide groove 9 is slidably connected to the outer wall of the slider 14.

[0035] The top of the reset spring 12 overlaps with the bottom surface of the slider 14, and the bottom end of the guide rod 10 is fixedly connected to the side of the guide plate 8 by a mounting block.

[0036] A support frame 5 is fixedly connected to the side of the lifting and moving platform 2, and a side-mounted collection box 4 is snapped into the inner wall of the support frame 5.

[0037] The outer wall of the lifting and placing frame 13 is slidably connected to the inner wall of the guide plate 8.

[0038] The top of the collection box 16 is fixedly connected to a lifting handle 18, and the back of the lifting platform 2 is provided with a closed door 3.

[0039] The lifting moving platform 2 has a material discharge chute 7 on the side near the lifting collection component 6.

[0040] The working principle of this easily adjustable agricultural greenhouse harvesting track will be explained in detail below.

[0041] like Figure 1-4 As shown, this track system achieves continuous and efficient harvesting of crops in agricultural greenhouses through gravity adaptive adjustment and modular design. The specific working principle is as follows:

[0042] 1. Gravity-Adaptive Height Adjustment: When the collection box 16 on the lifting placement frame 13 is loaded with agricultural products, the increased weight causes the lifting placement frame 13 to move downward along the guide groove 9 of the guide plate 8 under the action of gravity, compressing the return spring 12. As the return spring 12 is compressed, the lifting placement frame 13 gradually descends, ensuring that the highest point of the crop growth point is always at a suitable height with the material discharge trough 7 on the side of the lifting moving platform 2, ensuring dynamic matching between the harvesting action and the crop growth height.

[0043] 2. Dual-layer collection box collaborative operation: When the collection box 16 of the lifting placement frame 13 is fully loaded, the system automatically triggers a linkage: the lifting placement frame 2 15 descends synchronously with the connecting rod to a position close to the standby position of the lifting placement frame 13. At this time, the upper collection box 16 enters the working state, and the lower collection box 16 can be replaced in time, achieving a seamless connection between harvesting and collection, and avoiding operation interruption.

[0044] 3. Guiding and Reset Control: The guide plate 8 precisely constrains the sliding path of the slider 14 through the guide groove 9, ensuring that the lifting and placing frame 13 moves smoothly in the vertical direction. The reset spring 12 pushes the slider 14 back to its initial height under no-load conditions, providing a reference position for the next round of loading.

[0045] 4. Modular Adaptable Design: The guide slide 10 can be quickly disassembled by rotating the slide nut 11, and the return spring 12 with different elastic coefficients can be replaced, thereby adjusting the system's load-bearing capacity to adapt to the harvesting needs of crops of different weights such as strawberries and tomatoes. The lifting handle 18 cooperates with the openable and closable door 3 to achieve convenient loading and unloading of the collection box 16.

[0046] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
